She doesn't get out of the car; that wouldn't be useful anyway, she can use her mage-sense to check things out just fine from there - she's mostly checking for people with obvious weapons or minds similar to the killer's.

There is in fact someone who resembles the killer outside the school, barely ten feet away from them.

Derek steps outside, oblivious.

...well, fuck.

She sets up a teleport trap between them and her tribemate and scrambles into the front seat where there's better cover.

"Ms. Blake, what are you doing here? Shouldn't you be in class?" 

"Oh! Hi, I was just, I mean, how are you?" 

She approaches.

Derek...glances at the car but doesn't do much else. He sniffs the air, and this doesn't make him look less confused. 

"How was your night?" 

She seems about to answer, but she triggers the trap instead.

She's moved back to her original position.

"Uh, Derek, what's going on? Is this like that time you got hurt, is everything okay?" 

"I don't know. How have you been spending the nights that you don't spend with me?" 

"Derek, this is ridiculous. Sokething weird is obviously going on, maybe I can help?" 

"I'm not sure you can. Maybe you should stay exactly still. Not make any sudden movements."

"Maybe not. Who's in the car?"

"No one."

"I can sense their presence. You could just tell me."

She might not know all those words, but the kobold is following along well enough that she definitely doesn't like this. And if this person already knows about magic anyway - yeah, let's get another ten feet between them and Derek.

"Derek, please tell me what's going on."

"I'm not sure I will, Ms. Blake."

"Run."

She runs.

"Kobold okay?"

She nods, wide-eyed.

"Kobold understand memory? Memories is understand before. I have memory of kobold home, of teach kobold English, of kobold help me eat food. Kobold have memory of kobold home, of my home, of learn English, of help me eat food, of murderer and victim before."

She nods again.

"Kobold want see my memories?"
