Asylum of the Daleks

My theories:
1) Oswin Oswald is somehow connected to Oswald Dane from Torchwood: Miracle Day
2) Oswin had traveled with the Doctor before this episode (I like this idea because then the Doctor has to deal with knowing how she will die), but doesn't seem to remember him becuase:
a) she knows this is before he meets her and is pretending she doesn't know him
b) She has forgotten because of her dalek conversion (the other people didn't really remember)
c) She erased her memory of him (maybe too painful?) like she will do with all of the daleks
d) Timey-wimey-she erased the daleks memory, which erased hers, then she somehow traveled back in time to before she had done it??
e) The daleks erased her memory of him so that she could be an excellent trap, which is how she knew how to erase the memory.
3) Oswin Oswald is not the same character who will be the companion later in the series. It is simply the same actor

Observations:
1) The dalek conversion seems an awful lot like the cybermen upgrading.

Other theories I've seen online:
nerdgirlstash on instagram- the Doctor will go back in and try to get her before she gets captured by the daleks. Or somehow the tesselecta is involved.
samlock93 on instagram-Somehow she finds a way out of the explosion and managed to become human again.
matthewhpg on hypable- "Here's a crackpot theory for you: Take a look at the chair Jenna-Louise Coleman was sitting in throughout the episode, it was the same one that the Doctor's daughter, Jenny, sat in in the ship she took off in in "The Doctor's Daughter." Do you think Jenna-Louise Coleman could be regenerated Jenny, or is BBC just reusing an old prop?" (I really like this theory!)

What are your thoughts and theories?
