House tells Cuddy, "Your hypochondriac mom had a brush with mortality last month, and it's understandable that you're worrying more than usual, worrying that you might turn into her."
House uses mute expressions to communicate his assessment of a differential diagnosis session's direction. The expressions are very similar to Rowan Atkinson's Mr. Bean. Hugh Laurie and Rown are long-time friends.
Taub's wife mentions that her brother broke Taub's nose five years ago when he discovered that Taub had been cheating, but Taub comes clean about his infidelity after he had started working for House, less than five years before.
