I recently just got into watching Doctor Who from series 1 and onward. The reason i decided to watch doctor who was that i started watching torchwood not knowing it was a spin off to doctor who. After watching a few episodes of torchwood, i read the general description of the series on netflix streaming, saying it was a doctor who spin off. So i wanted to know how it fit together. I stared to watch doctor who. Now that I finish the recent season of doctor who, i got a question about the new companion Amy. Why doesn't Amy remember any of the recent events on earth from the past season? Not sure if I miss them explaining it. Does that mean with Amy not remembering, that those past events didn't happen?
