For now (a mini headcanon)
Mick’s not planning to give anyone the coldgun. It’s a memory of Snart, a reminder of him not being able to trust anyone at all - because everyone will betray him sooner or later and everyone will leave. That’s not something Mick’s interested in again. But not something he would want to forget either.
He has the gun stashed away in the trunk at the end of his chair, his feet propped on it, a barrier in case Snart wanted to crawl out of whatever timely grave he is in and claim what’s not his anymore.
He thinks about burying the gun - if Lisa can’t bury Snart’s body, Mick could share the place where he buried at least something of his, a place for Lisa to mourn over. Yet the idea still doesn’t feel right. Maybe Mick just doesn’t want to share.
That’s why he’s more than surprised when something about Haircut’s pitying expression makes Mick move, makes Mick reach inside the cursed trunk. No, Haircut’s not an outsider. He was never meant to be one, not with that hopeful face of his, not with his devotion of being good, not with his desperate need to be recognized by someone. No matter whom. Haircut just needs someone to see him, needs to feel he’s not invisible to the world - Mick understands now why the Time Masters didn’t want to kill him off right away. If one let that go on, if one let that stew for a while longer... Haircut could turn into something dangerous, spiteful and twisted.
And that thought doesn’t sit with Mick as much as Lisa having access to the gun doesn’t, so Mick tells himself that’s the only reason his fingers curl around the coldgun. Not because he wants, needs to do something, to make sure the hopeful stupid smile still has a chance of appearing on Haircut’s face.
He points the gun at Ray and tells himself it’s the last chance to back off. It’s a chance that he should take, because he knows it’s a terrible idea, he knows-
“What are you doing?”
Haircut’s not afraid, he’s confused and Mick grumbles. Damn it.
“Something I hope I don’t regret.” Mick says before he has time to think about it, his drawl all but forgotten. He’s doing a mistake, he knows.
But the thing is... maybe he’s not.
“This belonged to the greatest outsider I’ve ever known.” If Haircut needs to be recognized... if Haircut needs someone... then maybe Mick can share the gun. But he wants something in return.
“I’m looking for a partner.”
Mick has no idea if Haircut knows it’s a contract when he takes the gun, it doesn’t matter though.
What Haircut will know, is that Mick is the person that sees him. He’ll know that he can be outsider with Mick and that’s enough.
For now.
