There is no scenario that would be believable of House letting Wilson leave him, There is a very famous clinic: Cleveland Clinic .
Top Notch medical my friend in Ohio says?
Ive also noticed the jackets/clothing thing House is definitely wearing Wilsons.Im guessing "sleepovers"
Ive noticed other stuff like that throughout series, These next few episode promise to be very emotional.
Wilson is the person that matters most to House,And same holds true of House for Wilson,A love story doesnt get any better than this.
