What is he going to do? There's only one thing he knows to do, and it's been held far outside of his reach. The only future he has, the only need, is with his master - the one who has his Name. If he can't serve that purpose he has no purpose and he has nothing.

"I didn't get anything," he says, as if that is relevant to anyone. Well, he did stuff a few things in that pocket dimension, but he doesn't even know how to access that right now. "I know I can't do it, so just... let me go back. I'm... I'm not worth anything."

He's not even really a person.
