Dr. James Wilson: When you do what I did, it's not enough to tell yourself you did nothing wrong. You need to hear it from someone else. If not God, or society, a friend. Otherwise you go crazy. What you said to me up there, thank you. You're a good friend. Cuddy should know that.
Dr. Gregory House: You should let her know I drugged you so you couldn't confess to murder.

Speech, speech!
14 November 2009 | by (United States) – See all my reviews

House, Wilson and Cuddy attend an upstate symposium, at which Wilson is to deliver a speech. Back at the ranch, the crew deals with a teen who, after a wild night out in the city, develops swollen appendages followed by a heart attack. Problem is, she will not tell the truth about her wild night out, so the crew is at a loss in trying to figure out the cause of her condition. House has to help via cell phone. A little too much soap opera nonsense as House pines for Cuddy and Chase has marital problems stemming from his deep dark secret (remember the African dictator episode?). Still, not bad for a sixth-season House episode.
