We were watching Harry Potter and the Goblet of Fire after DS7 finished the book last weekend. He was ofcourse plenty mad with the movie since it was so different from the book but was looking forward to the part at the end when it is revealed Mad Eye Moody was really Barty Crouch Jr. DS went quiet all of a sudden when we got to it and then turned to me and said "But that is the Doctor from Doctor Who"
He loves Doctor Who and David Tennant so was quite disappointed to find he was the bad guy ;-)
