Mick is on edge because there is absolutely nothing for him to do. Nothing he's needed for. No, he's been pacing the safehouse like a caged animal for the last half day and he is utterly done. A hand reaching for Leonard, some way to distract him if only for a little while. To get lost in a different sort of heat. Touch. It's been so long since he's done more than lay beside his partner, even trying to tangle their fingers together is shaken off or ignored these days.

Every time he's pushed away. Ignored.
Not needed.
The job is planned down to the letter and he can't even take a moment for them because he doesn't need it like Mick does.

Mick spins away in a fury, grabbing the rest of his beer and downing it and it takes a tremendous effort not to throw the goddamned thing. "Stop ignoring me goddamn you."
