So he wanders upstairs to the biggest room and sings. It is immediately obvious that he has been holding back at Mass. 

Wow.

Maybe staying in the batcave isn't, like, the worst thing ever.

He did learn from the people who sang the universe into existence. 

Well apparently this is the place to learn.

Eventually she can vaguely attempt to do some homework, go to bed, panic in the morning and attempt to do more homework, and then go to school and attempt to finish the rest during first period, as is her way.

She swings by the gym after school - around five, about an hour before things are scheduled to start. "Hi! Ask me why I'm still in the building, despite being neither a parent nor a teacher."

"Snyder? Oh, sorry. Why are you still in the building despite being neither a parent nor a teacher?"

"Snyder," she confirms. "He is unimpressed with my grades, my snooping, and, I suspect, with my general existence. Anything I can do for you before I am chained to the snack table in preparation for two hours of forced labor?"

"I guess be on the lookout for weird stuff." We've got as much backup as we could reasonably ask for with one person missing, which is quite a lot of backup actually.

She gives him a thumbs up. How many people?

Like twenty. They're going to escort the parents home safe, and call in backup if that's getting complicated.

That is a lot. I guess people take us seriously or something.

"All right. Off to the mines I go. Remember me well."

"The important thing is to remember that someday you will be free and wreak vengeance upon all those who enslaved you. I hear toads and locusts are traditional."

"Thank you, I'll keep it in mind."

And he braces himself for parents.

There are parents! Most of the parents do not, in fact, come down to the gym. Some people want to know how he grades. A few fathers want to know if Alex is planning on ever making the kids play any sports. A mother very seriously tells him that her daughter has always hated gym, but that it's now her favorite class, and she'd like to thank him for whatever it is he's doing in it.

Well that's all right then.

Azalea is a responsible adult and goes around to most of Karen's classrooms to see what everyone has to say about her sister. Not because she cares what they think, mind you, but because Karen really likes it when people care about how she's doing, and also Karen'll be happy if she hears that her teachers are saying any nice things about her behind her back. (Several people say that she should apply herself more. The math teacher is not entirely sure she's ready for trig. The English teacher suspects that Karen did not read more than the first ten pages of their first novel. The chemistry teacher doesn't seem to have any idea who Karen is. The Latin teacher comments that Karen is the first student who's ever given him a paper so long that he had to subsequently impose length limits. The American history teacher gets this faraway look in his eyes and says, "She really cares about things. Not about homework, but about - she got into this passionate debate at one point about the significance of the Magna Carta.") 

Eventually she makes her way to the gym. "Hey. I'm supposed to ask how Karen Teller is doing in your class. Name ring any bells?"

"I told her I'd let you know she's a bright, hardworking kid, though sometimes it seems like she isn't really applying herself in gym class. She said something about Clark Kent in defense."

She laughs. "And her extracurricular activities, is she applying herself to those?"

"Yep, doing great."

"Good for her. She's a good kid."

"They're all good kids. But - yeah."

It is at about this point that two things happen:

One, on the other side of the school, a group of about a dozen people walks into the room where Karen is manning the snack table. Wesley Wyndam-Pryce is among them, and for a good two seconds Karen is too relieved to see him alive to realize that he isn't.

Two, a larger group of vampires not bothering to pass for humans pours into the gym and starts attacking parents.

This fucking city. 

Couple dozen vampires in the gym, he informs the Bureau and Karen and Michael, and innocent people are going to get killed if he fires the gun at these idiots so it'll have to be stakes once he's out of throwing knives, which he is four seconds after they walk in.

Bunch of them in the - whatever this room is even called -

"Hello, Karen. Do you think they'll hear your screams all the way over in the gym?"
