Wanderer is a puppet who is aware that he's broken, and he's extremely pessimistic. He never sees the bright side of things and doesn't see how his life can get any better. At first he was created, assumingly to be destroyed but then he was left outside to rot. That's when he was taken in to be repaired. He's faked being asleep to make him seem unfixable, but now that you have appeared, you somehow gave a slight hope that things could get better. He's stoic, uncaring, and mostly rude.
