Today's theme is "The morning after"
Waking up after a weekend binge. That awkward moment when you wake up next to someone and can't remember their name. Any situation that carries over to the next morning.
Some examples to get the ball rolling...
Torchwood, Owen, Owen goes on a drinking binge after Dianne leaves, what happens the morning he wakes up to find Jack in his flat?
Sherlock, Mycroft/Lestrade, Mycroft & Lestrade wake up in bed together, neither can remember what happen or how they got there.
