Captain Jack can’t die. Rory won’t die. Captain Jack loves Inato A LOT. (sorry if I spelt that wrong.) Rory loves Amy A LOT. There are too many similarities between the two characters. My sister pointed this out, and I thought up a headcannon from it:

When Jack left Torchwood, he was so distraught by everything that had happened, he threw himself into the rift in Cardiff, thinking it would kill him. What ACTUALLY happened, was that it gave him a whole new persona, and little kid’s body, and wiped his memories instead. So, he grew up and lived like a normal human. BUT THAT HUMAN WAS RORY. he grew up alongside Amy and Melody, and went on adventures with the doctor.
The spoilers saying that Amy and Rory are breaking up could be true because Rory gets all his memories back, finding out he is Jack, and that he doesn’t love Amy any more and leaves her.

Just a thought.
