How can Professor River song die twice?
River Song’s timeline does get sort of confusing because she and The Doctor always meet at different times in both of their timelines. At the moment the River Song that is in series five has not met the Tenth Doctor yet but the Eleventh Doctor is also not *her* Doctor. Because River always hints at being quite close with one of the future regenerations of The Doctor. River can’t die in series five then because she does die in series four and also that is a future version of River Song. I can understand it in my mind but it’s sort of hard to explain.
