I think Allyn's watching, but the only thing stopping him from averting his eyes is that the thought of not being able to see what's going on is even worse.
EDIT: I re-read the letter and I see what you're getting at--and I'll edit if you like--but given that I, the player, didn't remember the rule about not looking at the gargoyles, I don't think that Allyn would either, given the circumstances.
