house sister atau aunt

House is an only child. He says this in Daddy's Boy when he's describing his parents to Cameron at the end of the episode. He does have an aunt named Sarah, but she isn't even mentioned until Merry Little Christmas.

If you're referring to the "His sister voted for Nader...twice" komen made sejak Stacy, she was referring to Mark's sister. :-]

I think Stacey was referring to Marks sister [or aunt].

Stacy was talking about Mark's sister because they were talking about Mark's family history and stuff. That was around the time Cameron was testing for Alzheimer's and as well as fishing for some information about House.

House is an only child...at least, for now. anda never know, the writer's might come up with something in the future, considering the new twist in House's family history.
