7. Donnas Husband Turns Out To Be Real (Silence in the Library/Forest of the Dead, 2008)
Poor Donna, always getting the short end out of life. We know it, the Doctor knows it and she knows it. So it was a wonderful thing when she met a man and fell in love. When he turned out not to be real, it was very sad for her, but she kind of expected it. What she doesnt know, and the audience does, is that the man was actually very real. Donna missed out on a chance for true love and happiness with a great man and I cant think of too many things more heartbreaking than that.
