Thomas is appalled that evidence is required and simply for this remarks that it was probably destroyed in England.
Hal is making the big shrugging Really Bitch? face right now because his whole fucking career the past near decade should be proof enough you redheaded little twit.
Silver considers the request for proof one of the more valid things Flint has requested of him and just gestures vaguely to That Verse.
Vane doesn’t believe he needs to prove a goddamn thing, so let me gesture to that verse for him.
Theodore is not at all surprised that Flint requires proof, because, and I quote, “For a man of such big and wonderful ideas for the world, he is held back primarily by his inability to see himself in that future, because he lacks the fundamental capacity to forgive himself enough to allow it. So long as he considers himself a criminal against his own heart, he cannot comprehend the idea that broken piece of him is deserving of tenderness.”
So there’s that.
The only others who have interacted with him haven’t killed him so I mean, that has to account for something. Also Julia says the proof is in how many of her shirts she let him steal as a wee bairn.
