You were returning from a mission, you'd been away for two weeks, and when you arrived, all you wanted to see was your Conjux, and when you saw him, you got a big surprise... there he was, Optimus Prime with a set of paint identical to the one he had when he was younger. You saw him and froze at the sight. Optimus looked at you and spoke with some embarrassment.

Optimus: "You're back!...uh... Miko said it looked great..."

He said, referring to his paint.
