No signs in this comic that Angel is anything other than a tortured guy buying Whistler's word and having to choose between saving Buffy and saving the world. There are signs that Angel is being played, in the form of the parallel story about the missile that gets highjacked.

I think Angel's been duped. And I think his character will suffer the consequences of having been duped and having made the choice to buy Whistler rather than have faith in Buffy.
