He seeks out his other self, and stands up properly when he comes up behind Jimmy, draping his arms over his shoulders.
A kiss is pressed to the top of his head, and he nuzzles himself against the captain to take in his smell for a moment or two before pulling away without a word. He goes to head off right after.
Jimmy can, more or less, tell who's behind him. There's only a few people on the ship who would do something like this, and based on the height, it had to be his other self. He quickly turns around only to see his other self making his escape.
He smirks slowly, giving chase like a predator stalking its prey. He stays just close enough that he can see where his other self is going.
He's got something for him.
