Him not doing a fresh restart as a way of character building is great… up until the point that he does do a fresh restart. It’s a Deus Ex level trump card that he can play at any point, and we the audience cannot pretend it doesn’t exist, because it’s already been established. As a result, no matter his growth, we know that he’s never actually up against the wall.

If he actions himself into a corner, he does not need to think a way out. He can just jump. And he does.
