On Oswin...
Okay, so we were promised the spunky, tiny-nosed, well-bosomed new companion at Christmas, then what-do-you-know, she's in the premiere. Then she's a dalek and then she asplodes. God bless your sadistic sense of humor, Mr. Moffat.
I never worry about Moffat's women. This is the man who gave us Sally Sparrow, River Song and, my personal all-time favorite, Madame de Pompadour. And that to say nothing of Irene Adler or Susan, Sally and Jane. So, my biggest concern in losing Amy was not that we'd end up with some lame new girl but that we're losing, aside from the brogue, the skirts. I like the skirts. Apparently, there are people who don't like the skirts. I don't understand those people. I was sad that they were going away. But then, I saw Jenna-Louise Coleman in a sweater and all was well in the universe.
Until she asploded. Like, big time went BOOM! Also, she was a dalek. I'd say that was an even bigger problem, but she got plenty of air time before anyone figured that out. Still, though... dalek. A dalek that got blown up. That's a lot of hurdles to get over by Christmas.
Naturally, there's speculation galore and here's mine: the last words she said, "Remember me." Moffat covered this in Series 5, when Amy remembered the Doctor back into existence. It's a bit sappy, but Oswin is coming back in the Christmas special and if there's one thing a Steven Moffat Doctor Who Christmas special promises, it's tears. Last year's special was just one extended tribute to C.S. Lewis and being a mom. Come on, who wasn't inspired to phone their mothers after that?
So, I predict that the Doctor will be faced with some peril that requires him to remember up some assistance and, just like in Let's Kill Hitler, he'll reject the stock photos of his past companions until he gets to Oswin and then she'll be real again and brilliant and off they go.
