For Beth, Kieren isn't a walker. Not in the sense she's used to them. Her father TRIED to help them and it became really, really clear when ever mother tried to eat her face off that it wasn't possible. Kieren is something of his own and that wouldn't change how she would react to one of the walkers from her own world coming to Darrow. She'd still kill it.

Hahaha, I don't know! Philip doesn't know Lito that well, so he might not be able to place him based on mannerisms or things like that, but it would depend on how Lito behaved.

SOON. He and Finch will talk to her in the next little while and go from there. >:D
