harry potter and the goblet of fire
harry's parent's house
There is a House Elf and his name is Dobby.
No, James Potter was in Gryffindor house. Harry's mother was also in Gryffindor.
Harry is a Horcrux, If Voldemort tries to kill him he only kills part of his own soul, which then makes Harry a Normal but still Famous Person and gives Harry the option to Die or Live on... He Lives on.
Slytherin.
