I killed him, the Doctor. Some might say I killed him twice, but I actually did the first time. Even when he was dying he...cared. About what happened to Amy and Rory, what happened to me. I gave something up to bring him back, and I've loved him ever since.

They pulled me back in. I had to watch myself kill him again. I went to prison for it.
