Adrian Monk: I'm not quitting. I'm in too far to quit now. Look, we're close. We have the who. All we need is the why. Right? Why do they want to kill the old guy?
Natalie: You know what, we're calling Dr. Bell.
Adrian Monk: Why?
Natalie: Because you're enjoying this way too much. I think you like scaring people. I think you've been so repressed and powerless for so many years, it's just gushing out of you. You are not yourself.
Adrian Monk: Or maybe you're meeting the real me for the first time.
Natalie: Mr. Monk, that was Harold Krenshaw you were pushing around this morning.
