Daylen has no reason to trust this former almost-templar he's gotten stuck with. He's not sure why he finds himself doing it anyway, but while he's figuring that out, what's the harm in the two of them spending more time together? Or: Daylen has trust anger issues, Alistair has abandonment issues, and Zevran and Leliana are happy they're working through all that but would really like them to just kiss already. Barkspawn doesn't care, so long as they're petting her.
