I just listened to Bill's interview about Jodi growing pot on the roof, then her parents going through everything in her room. After that she "changed". She would not allow her parents to stay with her in Palm Desert because she was afraid they would snoop through her things in that home. Lying about everything, hiding things, keeping secrets.
So the "betrayal" that Jodi felt from her parents is what invokes her rage. Anything that Jodi feels that reminds her of "betrayal" is what triggers the lying, hiding, cheating, stalking, sneaking, computer stalking, text stalking, and any other sort. Interesting how Jodi couldn't put herself in Travis' shoes when he confronted her about snooping, stalking, and hacking behaviors. Jodi couldn't feel the "pain" of her parents doing this to her when Travis tries to explain the pain she is putting him through.
This is where she learned power and control over others - find out and expose their secrets.
