You're welcome ... thanks for making it. I've had people wonder how I got an Oswin tee so fast after the episode. And today my workplace manager passed me and started reading it, then looked away, realizing that it made no sense to him (not a fan) : )
Here's an idea. Oswin is this season's Bad Wolf. The Doctor will run into versions of her with different but similar names and different outcomes. In the Xmas special she will be revealed as a being who splintered herself into several parts across the timeline (genius, remember? Or maybe the Doctor causes it). When the splinters die, they reintegrate into the original Oswin.
