It's a loyalty thing.
Harry said quite a few times while he was in the house that Aaron was his best mate in there but when he comes out of the house and tries to run him down it's just a bit dissapointing to some of his supporters.
They played the game together in there and it was almost like Harry was doing the "well if i can't win i'll try and spoil it for him".
Just not very cool really.
