Adrian Monk: A year goes by. You decide that life would be perfect without Sidney Teal around. So you two hatch a plan. You contacted Sidney, and you reminded him of the time you helped him impress his date, and you asked him if he wouldn't like to return the favor.
Sharona: You knew he wouldn't say no. It was a chance for him to relive one of the best nights of his life.
Adrian Monk: And it worked like a charm. To the rest of the world, it appeared that an eccentric billionaire had a nervous breakdown. And if worse came to worse, and anyone connected you with Sidney Teal, you just had to admit that you'd had an affair and claim that the shooting was self-defense.
