Amy Pond
In "The Wedding of River Song," Amy leads a secret organisation. Rory works for her. The Doctor and River meet again in an alternate reality after River stopped the Doctor being killed by the astronaut. Amy remembers all of her past with the Doctor but cannot remember Rory. Amy finally remembers Rory when she saves him from the Silence. She kills Madame Kovarian for taking away Melody. Reality is restored when the Doctor and River marry. Amy and Rory are back at home. They have had no contact with the Doctor since "The God Complex," but they still remember the alternate events. Later River tells Amy that the Doctor did not die in Utah and is in fact alive.
