In the process of "saving" Gabrielle Delecour during the Second Task, Harry becomes "soul bonded" to Fleur's younger sister. This is met by almost universal distaste by the general populous, and revulsion from Gabrielle's family, seeing it basically the enslavement of a eight year old to the whims of a English child. The fickel Hogwart's student body ostricise Harry, calling him a pedo etc... Harry wants none of it, and desperately looks for a way out. He becomes further incensed to find out that the only apparent way to break the bond will cause Gabrielle to go mad and die. So Harry is stuck, either never getting a choice at love before he even goes on his first date or murder an eight year old.
