Angeal can still understand them, understand speech and body language and the way Zack was giving off agitated worry. It is rousing him, the more human part of him at least- the one he considers more monster than the rest of himself, what he had become.

They are trying to save him. For a moment, Angeal wonders if he should lash out or leave- he doesn't want to, he just wants the end and for it to be over, since he had been unable to save his friend from... from himself. Fuzzily, the details seem strange and he was not sure why, Angeal was finding it hard to think in just reflecting, much lest anything else.

Another soft noise, before Penance turns to face the two of them. Even with no other eyes then the unopened ones, he still finds them easily, tracks them with a considerable amount of effort, considering his injuries.

Something has to be done, be it he does it himself, or them.
