"Hey, hey, hey. Look at me. Look, you're not as bad as you think. I've only just met you, but I can tell you're useful. You helped me dimension-hop for god's sake! That's hard as hell to do! Trust me, I know. I used to be able to do it. Not to mention, you just did it without a second thought? I don't know anyone else who would do that for a total stranger. Listen, I know for a fact that you're useful. Everyone is, in some way."
