John hands Sarah Silberman's address and hurries out the door. She then notices the tape in her bag is missing. She finds it John's VCR. She pushes it in and watches.
Inside Pescadero, a DCFS agent puts a document before Sarah. The papers waive all parental rights to John. Sarah signs.

Derek stands in the yard, barefoot. Sarah tells Derek she's headed out to find Ellison. Derek asks her about Kyle and asks where his body is. Sarah says she'll take him one day.
Silberman crudely tourniquets Ellison's wound. Silberman speaks like a mad man about the apocalypse, and remembers when the T-800 came to Pescadero to save Sarah. Ellison listens closely and asks him more questions about the day Sarah escaped. Ellison tells Silberman that he came for his help, and he could prove that Sarah wasn't crazy. Silberman opens the trunk of Ellison's car and finds the T-888's hand inside a cooler. Silberman knows the hand must be destroyed, and then he drugs Ellison.
