Ultimate Jenna Theory

So here is my ultimate theory for Jenna–Louise Coleman's character.

Clara and Oswin are the same person, Asylum of the Daleks is the story of how she dies. She meets the Doctor for the first time (from her point of view) in the 2012 Christmas Special. She and him travel together for years, and eventually part company. Somehow, some way, she ends up losing all her memories. She has no idea who she is, or that she ever traveled with the Doctor. She makes up the name Oswin Oswald (not knowing her real name, Clara) and joins the starship Alaska to see the universe. It ends up crashing on the Dalek Asylum, and 363 days later, the Doctor, Amy, and Rory arrive. At the end, Clara/Oswin dies when the Daleks annihilate the planet. Moments before she dies, her memories come back, and she tells the Doctor to remember her so he will treat her well during their travels together.

The Doctor, never having seen Clara's face at the Asylum, never knows it's the same girl he took traveling. He never finds out what happens to her after they part ways after traveling together. He never knows the girl he met who became a Dalek was his dear friend Clara.
