When someone has to tell him to put his blaster away, even or perhaps especially when they're right, it just makes him want to keep it out that much more. If only to be contrary. He's grumping internally as he puts it away and because it's Han we're talking about, the look on his face emotes perfectly what he's feeling.

"I arrived earlier today." Han confirms. Not especially keen on giving up information about himself, but it would be easy enough for anyone to tell that. Especially with him not having hidden the falcon.

"What about you. You been here a while?"
