As the boys debate the plan, Jude's estranged mother, Lydia overhears and confronts Kes and threatens to tell their father.

Kes and Michael get in Callie's car and chase them, but the brakes have been cut by Jude and they go over a cliff, leaving them perched precariously on a tree on the side of the cliff. Callie manages to rescue Michael, but as she tries to rescue Kes, she slips and is left dangling from the car. Jude rushes to "help" by grabbing Callie's hand from Kes. Jude intentionally lets go of Callie's hand, who still manages to hang onto the car with her other hand. However, Jude loses her balance and falls to her death.
