Paul Wellman: That's right.
Adrian Monk: Are you sure about that? About the lights?
Paul Wellman: Yes, sir. I'll never forget it. I turned on the lights and saw the blood.
Natalie: Why are you asking about the lights?
Adrian Monk: Who turned them off?
Natalie: Oh. Yeah.
Captain Stottlemeyer: That makes things a whole lot more interesting. Let's seal this building. Talk to everybody.
