My new beginning!"Kyle heads out of town. He has an inappropriate relationship with his ex-girlfriend/party girl, Angela.Sarah overshares and tells Helen about being an Orphan with her best friend, Jennifer. They were never adopted.

Sarah writes a goodbye letter to Kyle and drives off with Helen. (Who packs a gun and some drugged water.) Sarah doesn't tell anyone where she is going.
