Snark followed by sex followed by snarky cuddles. I don't care when, where, how, or why, just Rebecca tossing Shaun down and having her way with him. Consensual, of course.

Bonus points if someone walks in on them
Extra bonus points if Rebecca still has her headphones on
Deluxe points if they've been in a relationship for a while - Lucy isn't startled, but Desmond is entirely confused because his knowledge of romance doesn't include casually hurling insults at each other.

Because there is no way that Shaun and Rebecca didn't share that generous double bed when they were alone.
