Venomous

Wesker lives, is stable, and makes a deal. He will remain in the shadows and not return to his old aspirations but in exchange he wants one thing, Chris. No tricks, no mind games, just 24/7 access to his old nemesis.

Chris is understandably untrusting but once he calms down, he starts using his free time in between missions to visit with Wesker in his remote place off the grid. Overtime, their relationship starts rebuilding until it finally boils over.

This takes place months into their arrangement.
