The police nailed down a pattern - the guy found with the missing bones was one thing, but there were other missing persons, alternating genders, late teens to early twenties, all taken from the same part of town. Cops, including cops of the relevant age range, stalk the area, and one of them gives chase to a man who proves to be a firebender. He burns out most of a liquor store, proving it, and the cop loses him trying to meet him on the other side and goes back to help evacuate the units above the store.
There's security footage of the fire and some of the chase, rescued from the liquor store, and the media gets ahold of it.
Chali says this still isn't an Avatar matter. Beila, who has no detective skills anyway, defers to his expertise, meditates, reads her book - turns up to her firebending lesson.
"Sure," he says. "In that case, I have something for you to pass on. You know that firebender who was on the news, attempted kidnapper, suspected murderer, burned out a liquor store fleeing from the police? I recognized his training. There wasn't a lot to go on, but I'm very familiar with the style. I looked it up; the man I'm thinking of died three years ago, in his house on Ember Island in the Fire Nation. Apparent suicide. They suspected his second son of having killed him and run off - practically a family tradition; the first son set the house on fire and ran off twenty years earlier - but they couldn't find anybody who'd admit to having met the kid, and the evidence for suicide was pretty strong, so they gave up the search. I'm pretty sure the guy on the news is that second son."
"His name's Sora Oshiro, he was born on the sixteenth of Rain in 594, and that's as much as anybody knows about him because after that he was apparently raised in total isolation by his father." He sighs. "Except I have a few guesses to make about what that was like, because the first son was me, and trust me, setting the house on fire and running was a pretty reasonable response to my dad's idea of parenting. Dad wasn't a firebending teacher, he never just took students; I knew as soon as I saw the video, the only way anybody else could be running around with his exact bending style was if he'd had another kid. So I did a search and there it was. I'd... really rather my part in this story didn't hit the news, at least not with any connection to me. If a bunch of people start wanting to talk to me about my dad, I am going to have to abruptly retire and go be an anonymous hermit somewhere. But I'm willing to tell you if it'll help get this guy found."
"...If for whatever reason you end up going after this guy yourself and want to have me with you instead of or in addition to a police squad, I'll go. And as much as I don't want to have this conversation twice, if you come back to me with questions I'll answer them. But I can't think of anything else right now that seems like it would help the investigation any."
And she goes.
And she tells Chali.
And Chali does the obvious thing and looks up Sora Oshiro.
Who has traveled to Republic City, among other transactions, under his own name. That's certainly... interesting. But the financials don't immediately turn up where he's staying. They quietly release a description which... basically describes Jun, only two decades younger, but with low confidence and not much fanfare. They don't want the killer to know that they're onto him (or, if Jun is wrong, that they're busily barking up the wrong tree).
Chali appreciates the tip, keeps the Jun connection otherwise quiet, and sends Beila home. She goes. She finishes the Avatar Meixing autobiography. There's a bit about the Avatar State.
From the sound of it, there are no practice effects at all between the startle reflex Avatar State and the fully mastered kind. They're totally different things that simply both happen to involve glowy eyes and supreme power.
The way Meixing describes it, both of the avenues into the state are, well, mental states, but they're unrelated. There's no reason Beila shouldn't be able to just... do it.
That said, "while fretting about a serial killer who may be her firebending teacher's little brother" is not the ideal time to do complicated mental work, especially of the "calm yourself, empty your mind" variety. She sends a message to the nuns. She can't drag her big mirror out to the beach without teaching herself to metalbend or her dad's help, so she goes over katas she already knows rather than working on wings.
Chali's not home yet when she wants to go to bed. Ranyi's waiting up. Beila gets sleep.
Free time and no plans with Beila means woodcarving in the park. Highly preferable to sitting at home; the park is nice and the weather's good. So Dao sits and makes necklace charms, little wooden this-or-thats arranged suitably to be strung on strings. He wants to make a little roc that is not just any little roc but a little Liqing in particular, and it's hard, but it's the fun kind. When his failure to portray the particularness of his girlfriend's bird starts getting to him, he takes a break and makes little ottercats and ferretsnakes and lizard crows and flying lemurs.
He's pretty sure this isn't him turning into a serial killer, because look at him, not doing that. But it's still not a train of thought he wants to keep revisiting.
He puts away his knife and his little half-carved pendant of a coiled-up ferretsnake and—tries to get up. It's less successful than he was expecting. He tries again. Maybe his clothes got caught on the bench; he twists around to check.
That smile hits him like a bucket of ice water to the face. Instant chills. Before he consciously catches up with the situation he's already trying to reach for his bag, but now his body just plain won't move, and he finally clues in. Bloodbender. Actual real live bloodbender. Oh, fuck.
Dao finds himself taking it, finds himself picking up his bag with his free hand, standing gracefully, following the stranger away from the bench. It's not like in the movies; he doesn't jerk around stiffly like someone who is obviously being bloodbent. He's only clumsy when he struggles. He manages to stumble and fall, trying his hardest to resist the imposed movements.
At least, that's what he hopes his reasons are. The same part of his mind that has inappropriate reactions to thinking about ripping people's bones out is having an inappropriate reaction to the sensation of being subtly, insidiously, helplessly puppeted by his own blood.
Okay. Crap. What does he say.
"...Want some more animal trivia?"
Great. Yes. Awkwardly semi-flirt with the bloodbender. That'll help.
He feels himself walking around inside a quiet house, going down some stairs, walking around some more, and then sitting in a chair. Somebody ties him to the chair. Then nothing else happens for a bit.
It takes him several minutes of extended internal debate before he finally opens his eyes, fear of not knowing what's going on having won out over fear of what he might see.
His first impression is of lots of bones, and then the bones resolve into a huge figure of a spider, half-finished, menacing and somehow ethereally beautiful at the same time. He stifles a shriek.
By the time he winds down, he's not even sure the bloodbender is still in the room. His face is wet with hysterical-laughter tears, but his hands are tied down. He tries to turn his head and wipe his face on his shoulder, but can't. Okay, bloodbender probably still around, then.
"Look," he says. "Can you just - can you give me some credit here?"
"I mean you're acting like the only reason I'm trying to convince you to stop kidnapping people and making statues out of their bones is because I don't want to be art materials, and it's not. I'm - you're not the only artist in the room," he says, and somewhere in the middle of that last phrase his voice turns soft and tentative.
As the silence stretches, he gives up on trying to make it nice and settles for making it real.
"When we were sitting in the park and I felt weird about you being there, I kept thinking about stabbing you," he says. "I wasn't going to - I'm not - I've never actually done anything like that. But I think about it. A lot. I think... it's something I could do. I could be the kind of person who does that, if - I don't know what if, I've been going nuts for years trying to figure that out, because I don't wanna cross that line but it's kind of hard to avoid it if I don't even know where it is. So. Don't say 'art'. Why are you doing this?"
Even once he can turn his head, there isn't hardly anything to look at in the gloomy basement except for the bone spider and some bloodstains on the bare concrete floor. At least he's pretty sure they're bloodstains. He tries not to think about it too much, because his reaction is half terror and half - inappropriate.
But he doesn't really have anything better to think about.
There's the fact that it is - or was, before he totally lost track of time - the last day of school for the week and nobody's going to miss him for two days, that's a great thought. Or how about the fact that he might've just blown his chance at talking the kidnapper down by being an awkward dumbass, he could think about that. And if those aren't enough, he could think about how upset Beila is going to be when somebody at school finally reports him missing and she realizes that he's probably had his bones stolen, but it's too late to do anything about it! By the time he's been trying to drag his mind off of that one for a while, freaking out about his inappropriate reaction to bloodstains is starting to look preferable.
"You're not very much like the other ones," says the bloodbender. "I'm not at all sure what to do with you." But he doesn't seem inclined to take suggestions, because he still isn't letting Dao talk. "I really can't let you go, you know. I have no way to trust you. Anything you say could just be a lie to secure your escape."
"I've been doing that, the thinking about stabbing people thing, for like as long as I can remember, and it's - I can't remember ever not hating myself over it. And I think. I've been thinking, lately, that maybe I don't have to? That maybe I can just - think the way I think, and not go around stabbing people, and that could be okay? And it's the most terrifying thing in the fucking world. The idea that I could be okay. That I could be allowed. Like I've been sitting here staring at your bone spider all night and the thought of being okay with myself still scares me more."
He discovers that he has begun to cry. He keeps talking anyway.
"It's, I don't - I have a really nice girlfriend and she's super smart and she likes me a ton, and, and she knows some stuff, about how I am, and she kind of seems to think I'm just, that there isn't anything wrong with me and there never was, and sometimes I feel stupid for not just getting over it already, but I don't think, I don't think you can really get it unless you've been there, I," he loses control of his voice for a moment and trails off into sobs.
A few seconds later, he pulls himself together enough to keep going, quietly. "And. And. Look. I just think. I just think, I don't know, m-maybe you don't care at all and I'm screwed no matter what I do, but if that's true, if you're okay with yourself, then I wanna know how you did it. And if you're not, then," he sniffles, "then I wanna try to help."
A short pause.
"It wasn't as simple as I thought. I don't have my father to be afraid of anymore, but I'm still afraid. Afraid of other people, afraid of doing things wrong, afraid of being noticed. I thought I could just figure out how to live like everyone else, and I mostly managed the practical parts, but... I don't know how to be okay. The only time I ever feel okay is... when I'm killing someone. And then afterward - I wonder if I really needed to do that, or if I just... wanted to make myself feel better." His soft quiet voice gets softer, quieter. "I don't like that. I thought... I thought that if I just did it enough, maybe the feeling would go away, and I could feel okay whenever I wanted, and it wouldn't matter. I thought that maybe, if I made it my whole life, I could feel okay all the time, and never be afraid again."
"Man, forget about letting me go, okay, we've got time to figure that part out, I guarantee you nobody's even noticed I went anywhere yet," he says. "Do you want a hug? Because if you let me out of this chair, I will give you a hug, and I will not try to run away, and even if I did you are a terrifyingly skilled bloodbender and could stop me anyway."
Dao hugs him, and murmurs soothing meaningless syllables, and feels very very strange about this turn his life has taken. But. This guy clearly needed a hug. He needs like an entire lifetime of hugs. Dao appreciates the value of hugs on a very deep level. He can hug the terrified serial killer.
"Honestly, right now, as long as I'm pretty sure you're not going to kill me in the next like couple of days, which I am, I want to be here more than I want to be running away. I want to actually help you, I don't want to get you arrested. You don't - I, like - if I was the one who was going around ripping people's bones out and you were the one who was - talking to me about it, I'd rather you actually talked to me and didn't run off and call the cops, you know?"
He's just glad it's dark enough down here that his blush is probably not visible, because that's just what this situation needs, right, a discussion of his inappropriate reaction to bloodbending, that'll help and will not in any way make the whole fucked-up situation ten times more awkward.
"Um. Thanks. I think I'm good now," he says.
So Dao goes upstairs. With the bone-stealing serial killer walking silently behind him. Which on the one hand is totally unfair and not something any reasonable person should have to do, and on the other hand, he's pretty sure he's genuinely less scared of this guy than this guy is of him.
The kitchen is as sad and lonely as the rest of the house. Dao finds the most uncomplicated breakfast food available, and sits down with it. He is dizzy and tired and hungry but at least one of those things is about to be solved.
He's not sure how long he sleeps for, but the room is a lot brighter when he gets up. He sits on the edge of the bed for a bit, and then feels a vague obligation to straighten things up in memory of how immaculately tidy the room was when he got here, so he does that, and then he sits on the edge of the bed again and feels very awkward.
"So... it occurs to me that like, nobody's caught you yet," says Dao. "So if you just stopped murdering people, they'd have a pretty hard time catching up to you, especially if you left the city and moved somewhere way far away and, I dunno, changed your name in case they find weird stuff in your basement after you leave, or whatever. Even if you don't trust me not to go to the cops over you, it still works, it's not like I have magic powers and can tell them where you decided to move to, you know?"
"I mean, I don't really know a whole lot about you, except that you're apparently some kind of waterbending genius - like, unless the thing where bloodbending only works on the full moon is just in the movies? And the thing where people stagger around like creepy puppets?"
"It's... it's the same," he says. "No - it's better—" and he abruptly lunges at Dao and hugs him tightly. The bowl of water is knocked to the floor and spills everywhere.
