House's House

House, Season 1, Episode 6, Actress Stacy Edwards plays a schizophrenic who turns out to have Wilson's Disease. Funny how she played Dr. Lisa Catera in Chicago Hope, and one of the first things she diagnosed was Wilson's Disease in one of Dr. Wilkes' patients. Anyone notice this or do I just watch too much TV? Also, did anyone else notice that House's address is 221B? Yes, it's Sherlock Holmes' address!
