A Cooperative Former Lover Day!
You slept together a few times, it was neither fantastic nor regrettable, but some words were said afterwards and you both decided it'd be best to cease all contact. Until today. You need his help.
No one knows safecracking better than your former lover. And you need the best. You've got the crew, you can get in and out of the basement no problem. But you need the magic key. You need a safecracker who can open that vault as if the combination was his baby daughter's birthdate. You need that guy you used to fuck for a little while to help you steal an amulet.
When he sees you standing there behind his screen door, that grin will flash across his face, that one that says "Well look who's back for another taste." In one split second, you can tell that there is about a 5% chance of the two of you fucking again before this job's done, and the only way that would occur is if the weather is pretty the night you all pull into the interstate motel you'll be using as your headquarters for the final leg of the job. That's the only night you can foresee having a few hours off. "I've got a job for you," say.
He'll get cocky with something along the lines of, you're offering me an opportunity? You need my help is what it is. I want 20%. You'll counter with 15. Then for the rest of the job, your crew will watch the two of you dance around the barely lukewarm haze billowing between you and think to themselves, "Those two might screw, but would it matter?"
Happy A Cooperative Former Lover Day!
