Erwin watches in horrified fascination as she shifts between herself and what the city wants her to be. Is that what he'd been like, when he was coming back into himself? He only remembers a searing, blinding headache, and then waking up feeling normal for the first time in days.

He tosses a bill on the tray the waitress brought, waving her away with a soft command of no change.

"I know you didn't. I was walking past and noticed you in here." He smiles at her, but doesn't reach out. He knows how strong she is--he's seen the splintered trees in the backyard next door--and if she's confused, she might lash out without realizing it. "I thought I'd come in to say hello, and see if you'd like to walk home with me."

All very polite, very nonthreatening, and not likely to attract any unwanted attention. Erwin's main goal is to get her out of here and back home, so that the worst of this will happen in privacy.
