There's a girl he's seen a few times, hanging around El the angry not-a-murderer, and it's pretty clear she's a mundie. He overheard their conversation, she doesn't know what she's doing. This wasn't enough to overcome his caution about El's cloak of doom and gloom, but now that he knows she's vouched for on the "not a serial killer" front...
He keeps an eye out at meals. Saturday dinner, he sees her in line, El not nearby, a dozen spots behind him. He slides back.
"Oh, hello, I've seen you in a couple classes, haven't I. Sit with me? We've got a good table today."
(He didn't quite catch her name - something-issa. Marissa?)
