Mick knows he's playing a role, playing his part. Even sitting away from the celebration he can tell that Leonard's heart isn't in it either. Probably because he had to go and be a needy asshole a few days back.

So he sits back. Drinks. Doesn't say much until the rest of them wander off into the night and it's just him and Leonard again. Same as always, but different as hell too and it's those differences that leave Mick foundering because he can't quite figure it out. What he needs to be doing.

A grunt. A roll of his shoulder. "Not really." Because he's going to use his words, goddamnit. "Not in the mood."

Liar, liar Mick.

He isn't strong like Leonard. Can't bury himself behind walls and pretend that he doesn't get lonely, that he doesn't need something as simple as touch.
But he's gonna try - for his partner. For what they used to be. For whatever they're going to be.
