The Honeymoon

House is convinced that just because Stacy married someone else, he can handle treating her husband. However, when Mark's tests come back normal, House is stumped as to why all the symptoms show that his brain is still dying. Wilson worries about his friend's emotional well-being and the entire team wonders if he can put his feelings for Stacy aside long enough to find out what's really wrong with Mark. Cuddy ends up adding to the dilemma when she ends up offering Stacy a reason to stay.
