Fine.
If he's going to be fucking dismissed Mick is out. Done. Leaving at least for the night and if Leonard wants to stop him he is more than fucking welcome to try, job or no job. He wants to act like this is no big deal? Sure. Mick is gonna call that goddamn bluff because he can read him like a damn book.

Boots on, reaching for his jacket. Because that was the problem wasn't it? Snart wasn't always like this. Not in the early days. Now it's all about control and Mick is just another problem for him to deal with and he hates it with every last fiber of his being.

"Fine, boss," he snaps back. "I'm out."

Just try and stop him.
