Morty knows he shouldn't be screwing around with multidimensional shit. It's dangerous, it's impractical, it's blah blah blah. But it's a potential key to unlimited energy, how does nobody see that? He's built a dimensional siphon (it kind of looks like a cardboard box with a funnel and a TI-84 taped to it, but it damn well works), keyed in the dimensional coordinates to a random plane, and by God he's going to use it.
He flips the switch and waits for the energy bar to fill up.
It does! It fills up very rapidly. Then it explodes, along with the box. There's rather more smoke than there should be, and once the smoke clears someone is standing there.
"Oh dear," Morty says faintly.
"Fubar's casual range encompasses everything from his tank to the nearest town over. If your hangups are that bad I can get one of the Mystic Arts instructors to ward you against telepathy, which will make your thoughts much less likely to get through. It's not usually very useful, because a determined telepath can get through a ward with a read or an attack, but in this case it'll make it much easier for Louis to notice that your thoughts don't want to be read and ignore them. I'd like to stress that it's more like being in a crowded room and hearing snatches of conversation for him than anything else, but I do understand that phobias are phobias."
"I do not consider my fear irrational. I would like this ward at the earliest convenience of whichever Mystic Arts instructor and then I will just try to avoid attracting the attention of any less polite telepaths."
"Any less polite telepaths should be reported to me for enormous amounts of discipline. I'll have Elyzia on it as soon as her Intro to Mystic Arts lecture is over, which should be in half an hour or so. Oh- and Louis would like you to know that he has been informed of your preferences and is currently putting his 'most Herculean efforts' into ignoring your thoughts. And that he would manifest astrally to tell you in person, but he wouldn't want to alarm you. Or accidentally focus on you in any way. And that he is now going to return to merrily trouncing Peter at chess."
"I appreciate that very much and if it is possible to inform him of this without drawing his attention to me in any way, shape, or form, that would be nice," shivers Bella.
"So," Mrs. Carson says at length, "we should probably set you up with some living quarters. You seem like you'd fit best in Dickinson, which is the cottage for non-monstrous female students, unless you happen to be on the LGBT spectrum and want a more directly supportive environment, in which case you would want to be in Poe."
Morty looks deeply confused. "Wait, I thought it was for the crazies."
"A popular misconception. Should I take your interjection as a desire to discuss your punishment for off-record experimentation with dimensional forces and the abduction of a sentient being?"
"No, ma'am."
"I'm gay but have not historically felt the need to seek much support from my surrounding environment for the condition; are matters particularly adverse here?"
"No more so than any other boarding school full of teenagers. Which is to say, unfortunately yes. As I mentioned, you have my personal protection, and absolutely no one will trouble you if they know what's good for them; if you would rather take that out of the equation entirely, you might prefer Poe."
"Which is apparently misconceived to be for crazy people, and your mad scientist here has already attempted to diagnose me with schizophrenia for twining my sister."
"I don't anticipate trying to date while temporarily stuck in an alternate universe, so let's go ahead and put me in Dickinson and I will be as stealth as the situation demands."
"Stealth is as necessary as you make it. Benefits of stealth include likely making some of your dorm-mates slightly more comfortable with you; benefits of not stealth include being able to glare conspicuously at casual homophobia and make the perpetrators feel guilty and slightly threatened. It's your choice. Anyway, shall we? Dickinson is half a mile east of here, if you'd like to teleport."
"I can take one passenger at a time when none of the passengers are my sister, do you want me to bring you?"
Bella takes her and Mrs. Carson half a mile east, a quarter-mile up so she can scope out the place, then puts them on the ground in front of the building under them.
"I'm sixteen. I'd be happy to audit some classes if you get me a catalog or I find somebody I want to shadow. I might also just want to spend lots of time in your library reading up on your advanced medical tech and deciding what I want in my gift basket, though. Can I get the location of your office in case somebody needs to be dropped off there for apocalyptic disciplinary action?"
She pokes her head into the building and looks around. "Ah, Miss Martin. May I have a moment?"
"Sure!" A girl soars out at high speeds and comes to a halt by Bella. "New kid?"
"Not quite. Mortimer Halliman accidentally summoned her, and she's going to be staying here until we can put her back in her home universe. I'd like you to show her around."
She shakes her head. "Ah, Christ, Morty. Yeah, sure, I can show you the wonders of Dickinson. What's your name?"
"I'm Ariel, codename Stormhammer. Current holder of the Blizzard Force, not that you know what that means considering you're from another universe. Basically, I'm a big-league powerhouse. Feel free to bask in my glory if you so choose. If you so don't choose, I can show you around."
(Mrs. Carson sparkles off back to her office for glorious, glorious paperwork.)
"My codename's Flicker, if those are customary to introduce oneself with. What is the Blizzard Force?"
"Carson gave you the whole Powers Theory spiel, right? It's this thing where a really powerful Avatar takes a whole bunch of spirits and mashes 'em all up into one big thing with more power, and they can keep doing that for their whole career. It's frowned on these days because, y'know, kinda inhumane to the spirits, but my mom was a supervillain and she wasn't real big on the whole morality thing, so she did it anyway. When she died I got the Force. It gives me a TK-7 supergirl thing, EN-6 ice blasts, and Wiz-3 magic. Plus I've got Ex-5 and Warp-3 gravity powers naturally. Basically, I break shit really hard."
