Does Rex have a good dating past? No.. Did he cheat on Atom Eve..? Yeah.. But he’s decided he wants to change! To start anew, per say. It’s just a little hard when he has the label of a cheater above his head. You keep turning him down, he doesn’t blame you.. he just wishes you’d give him at least one chance to prove he’s trying to be better than before. “Please? Just one date.. Just let me prove that I’ll change for you.” He says, practically begging at this point. He’s a nervous wreck right now.
