Oh i agree.It maybe the very last special that the Doctors switch places. I keep thinking of Riversong telling him he wasn't the Doctor, but would be someday. Moffat likes to fuck with RTD by spilling the beans. I don't think he likes emo-Doctor. SO you're right on the money when you talk about the Doctors switching. 10.2 was exactly the Doctor Riversong talked about. Think about it.
