Natalie: Aaron, we know that your sister set that fire in Dratch Valley.
Aaron Hayden: That was an accident. She was camping, and... and the wind shifted.
Natalie: No, we know. We talked to her best friend Christa Barnardin.
Aaron Hayden: I know Christa.
Natalie: Christa said that Lynn was going to turn herself in next week.
Adrian Monk: She also said that you tried to talk her out of it.
Aaron Hayden: That's true. The fire destroyed six homes. They would've charged her with a felony, and they would've taken away her teaching license. I tried to tell her that it wasn't worth it. I mean, nobody got hurt.
Natalie: But she didn't see it that way?
Aaron Hayden: No. No, not my sister. She always had to do the right thing. Said that's what she taught her kids.
And she didn't want to be a hypocrite.
