As soon as I posted that, I thought of one explanation that would satisfy me.
Just a hypothesis, mind you:
* Older Amy hated the Doctor with a passion
* After he lied to her and abandoned her to her death, she must hate him even more
* She's able to manipulate temporal technology, and has access to temporal engines on two-stream
* We only saw her be anesthetized, not killed
* We only have the Doctor's assertion that the treatment will kill a human. He may be wrong.
* Amy was not killed by the Silence in the White House bathroom. On the contrary, the Silence addressed her by name.
What if Older Amy survives and, twisted by her hatred for the Doctor, creates the Silence with the goal of having her own daughter avenge her?
Hmmmmmm?
In comments, please remember that I'm two or three weeks behind, and haven't seen anything past "The Girl who Waited."
