Billy's using the spare bathroom--he's not allowed upstairs, not yet, and Mike is putting salsa verde on his tacos when he hears it. The thunk from someone against a door, heard to him even with the shower running. He's not waiting to hear it specifically, but he notices it because it's familiar. Legs giving out. Shock over.

Mike stops what he's doing and makes his way to the bathroom. Pushes the door open, gently, and looks at the scene. Shower running, hot. Steam already fogging up the mirrors. Billy directly below him, having leaned against the door. His heads in his hands.

Mike has fucked Billy up and it it's him. He nothing, instead closing the door and sitting on the floor. There's a long while, just letting billy either compose himself or break down further.

And, after a beat, he wraps an arm around the other's shoulders and pulls him close.
