Re: Just watched Clara's first scene (spoilers)
Well beyond being the same hot girl? LOL
Although I didn't realize her last name is Oswin - they must be setting something up, honestly Moffat's who isn't that subtle, so either Clara gets left sometime in the past and forgets who she is, someone named Oswald is in the room and she's told "Her name's Oswin, Oswald." "Yes that's it, my name is Oswin Oswald."
