Dr. House (Hugh Laurie) and Dr. Wilson (Robert Sean Leonard) have been living together on House since House was release from the mental institution at the beginning of season six. And despite House losing and getting his physician’s license back, they’re still shacked up.

It’s a wonder they even speak with each other consider in the past two seasons, House has managed to cause the death of Wilson’s girlfriend Amber (Anne Dudek), while teetering on the brink of sanity – all with Wilson helping to pick up the pieces.

But, the friendship between them makes perfect sense to Robert Sean Leonard, who says House and Wilson’s special relationship is based on the characters’ intellects.

House airs Monday nights, 8:00 p.m. ET/PT on Fox.
