These are all situational scenarios, and in this example you can “punish” Pendles with a reveal, Orendi and Ambra do it best but five characters have methods of revealing him.
I can’t answer that and I hadn’t noticed, I just assumed that it would work on him since I’ve pulled OM out of stealth many times (and felt dirty about it) but if she can’t target him then good, she shouldn’t be able to either way.
