The ending is meant to suggest that Peter was behind the whole thing from the start. Considering that the lights go out when his hands are allegedly cut off, it's entirely possible that they were never cut off at all. I might not have made this clear at the end, but when Carol looks back, Peter is holding the fake severed hand with his real hand.

Thus, Peter was never the one being punished, but instead, used as a way to psychologically torment Carol. If Peter is the person who organised the trap, he definitely would have a way to escape it.
