Less immediately familiar than Queen, but still fun to play with!

Kareen tries more things—Beatles, more miscellaneous childhood-type songs like the alphabet…the Arrogant Worms are Canadian, right, does Chantal know Rocks and Trees?

She has heard the Beatles, and many but not all childhood songs, and not the Arrogant Worms. New songs are still nice to hear in their own way, though!

Which childhood songs that Chantal doesn't know are because of normal non-overlap and which ones are because she has a parent whose childhood was in the eighteenth century and she accidentally went too hard on songs not being from the future is something she'll only find out later, if at all. 

Eventually Kareen is going to have to stop, or at least pause, duetting with Chantal in order to do study group. She doesn't think Chantal currently has enough mastery of language to appreciate an audiobook, and she's not sure how Chantal would react to music that didn't respond to her, so she finds another mirror to put Chantal's with. 

Lonely doesn't really work. The Lonely is pathetically fragile; it is actually trivially easy to get someone out of the Lonely just by talking to them, but also it's one of the ones where if you don't manage that on your own you're most likely to have the freedom to get out via suicide. So she doesn't have any long-term mirrors up connected to Lonely victims. But with a little digging--pun intended--she can find someone trapped in the evil coffin who'd like to sing with Chantal. 

She looks out for April again at lunch. 

"Call me boring, but I'm really feeling a giant bowl of buttery mashed potatoes right now."

Giant bowl of buttery mashed potatoes. "Good news! Chantal is more or less fine."

"...what, for real?" She takes a bite of the mashed potatoes. "These are fantastic, thank you - did you, like, talk to her??"

"I more sang to her. She's not very verbal, but she sings--not with a human voice, mostly, but she outputs music--and emotion is one of the easier things to get across with just music. She appreciates the company but she's a lot less worn down by having been alone than I see in most situations."

"Wild. I'm, uh, glad she's doing okay, I guess?"

"It is pretty wild! If you happen to know the name of someone who went into the void less voluntarily, I'd appreciate it, I wouldn't assume they'd be as okay, but Chantal is doing alright. I'm very pleased."

"I don't know of anybody offhand. Shoving somebody into the void is a pretty big deal; I'm not sure it's happened since I've been here? Or if it did, I forgot."

"I'd heard it's precedented as murder but not as suicide."

"Yeah. Until Chantal I think people weren't sure it was possible as suicide."

"But you knew her well enough to know she was going to try?"

"I knew her well enough not to be surprised when I heard. Something like that was bound to happen."

"So, like, please don't construe this as me suggesting you should start a manhunt, but if you didn't specifically expect it, why do you believe it was suicide and not homicide when people knew that the latter was possible and not the former? People ever murder people who are depressed."

"Oh, I have my ways."

"Ohhh, okay." People having spooky ways of knowing things is perfectly normal and reasonable. 

"Thanks for the mashed potatoes! Good luck with all the weird shit you're doing!" And she's off.

Kareen checks whether her universe's Freddy Mercury is actually dead or suffering horribly. He is, thankfully, actually dead. She will definitely Rescue him at some point but he is kind of in line behind aaaaaall the people her dad killed. Well, all the people her dad murdered. Gertrude Robinson, who definitely counted as self-defense even if trying to kill Dad was objectively reasonable, can wait. ...Because she put Gerard Keay in the skin book, not because she tried to kill Kareen's dad. Kareen doesn't want anything bad to happen to him but she really can't blame anyone else for going "um."

More people ask for the Orion Special. It hasn't been doing the rounds as quickly as the pocket dimension did, once the first few takers vouched for it, because the behavior it encourages looks deeply insane from the outside, but people keep not dying and it is objectively incredibly desirable, so it's starting to pick up momentum. 

"There's like nothing to hunt anymore," grumbles Orion while he piles up an objectively unreasonable heap of pasta on his tray. "Except at night and it's getting so there's not much even then. It's like the beginning of term."

"There's gotta be a way into the graduation hall."

"Maybe we could make the school grind the gears a little faster and just walk in from the senior level."

"I've been studying the blueprints but I'm not sure I understand how we'd go about doing that."
