It's all AU.

Corwen had finally met up with John in the hotel bar. There'd been talking, rants and tears, and they'd both gotten extremely rat arsed as they'd both tried to put their immediate world to rights, talking drunkenly and long into the night about Jamie, Gray, immortals, and lost loves. 

Corwen had finally tucked John up in his own bed, after much coertion to get him there. She'd crashed out herself there for a few hours, before dragging herself down to the restaurant in search of some caffeine, a hangover cure and sober company.

She was sat at a table, head in her hands, nursing the worst hangover headache she'd had in years when she heard someone approaching.
