Not too hard, especially if she narrows to seniors. 

Good. She's making a list.

- And there's someone paying more attention to her, who seems intent on joining her for dinner. 

"It's an apple to sit down."

She smiles a bit and holds one out - a pretty good one, even. 

Fair enough. El takes it.

"Sure, then. Bored of sitting with... what is it, London?"

"Has been," she says, with a fond smile. "And not bored yet."

"You want something, then. Have a seat." The one next to El she'll protect, but Liesel can take any of the other open ones.

She'll sit across.

El takes a bite of the apple.

"So?"

"So," and her voice drops to a quiet murmur, barely audible over the hum of the cafeteria - just enough that neither El nor Lu nor Shinta need to lean in to hear her - "Have you found the seniors who tried to kill us all, yet?"

"Not yet. Not a lot to go on."

"I might have something that'll help."

"That was fast."

"I've had it for a while," she says.

"Waiting for someone to try killing us all?"

"It's a bit more general than that - I've had a lot of use for a spell for finding hidden enemies so far."

"That is a bit more general," El says, impressed.

Tiny preen! "It works fairly well, too - though it's easier the more clues the caster has to their target's identity, and also if the enmity is more direct."

"Hence why you're bringing this to us?"

"Exactly."

Hum. "What's the catch?"

"From me, or from the spell?"

"Both, since you so kindly offered."

"The spell's tricky - you need to be pretty good at clearing your mind of preconceptions, and it can throw wrong answers if you aren't careful."

"For me... Just kill them."
