Dr. Bell: Do you know what kind of poison he used?
Adrian Monk: No, they found the motel room he was using. There were some chemicals in the dumpster, but it'll take them weeks to analyze everything. There isn't enough time.
Dr. Bell: How about the food from your shopping carts?
Adrian Monk: No, all negative. No trace of anything. [coughs]
Dr. Bell: Adrian, I could have met you at home or the hospital, you know.
Adrian Monk: That's all right. I was out anywhere. Natalie is driving me to the cemetery to say good bye. I'm just so sorry, so sorry...
Dr. Bell: Adrian, you have nothing to be sorry about.
Adrian Monk: I have everything to be sorry about. I've lived like a prisoner. I've been a prisoner. Ever since Trudy... Wasted so much time. It's- Add it up, I've wasted probably 3 years just washing these hands. Wait. [wipes hands]
Dr. Bell: Adrian, you are not being fair. You know, You've been- You are more productive than anyone I know. You've solved over 120 major cases.
Adrian Monk: I didn't solve anything. If I didn't solve Trudy- I didn't keep my promise to her. Didn't solve anything. I always hated that painting.
