So, Keiran had found a room – didn't really matter where, beyond that it was in Britannia – and moped for a while, and had some really weird dreams about knights and kings and things. About Lexi, perhaps inevitably, though as with the flashbacks it both had and hadn't been her... he thought she'd been a man, which was all sorts of screwed up. Whatever.
Day two in Britannia, and he's decided to go for a wander. Maybe go round to The Round Table and apologise for being a twat about things, though he didn't see how saying 'I had a dream where you were a bloke and we shagged' would help things at all. Maybe just walk past and peer in and see if she was okay without saying anything, even if that was a little bit stalker-ish. Maybe just walk past on the other side of the road and prove to himself that he hasn't, in fact, fallen madly in love with the poor girl.
There are, as he passes, two figures there who definitely aren't Lexi, and he can't quite resist the pull when it comes to wandering over with a fairly-friendly, if a little who are you, where is she, what's going on? curious, “Hey.”
