Half Brother

Ben attends an end-of-year party with the Godwin kids and their friends. David informs Ben that his family is going to Europe for 6 weeks over the summer, devastating Ben. He goes for a walk, encounters Shannon, and walks her back to the group. Jennifer kisses Ben in front of everyone.

The Tomlins and the research team celebrate Zan's first birthday. A few days later, Ben turns 14, and the Tomlins go out without Zan. Peter takes Ben to a movie and tells him about Greg Jaworski, a linguist from Berkeley, who is joining the team.

The Godwins return in early August and invite Ben to the beach, but Jennifer barely interacts with him, choosing to flirt with David's friend Hugh instead, disappointing Ben. Greg Jaworski arrives and seems fascinated by Zan.

A TV crew from 60 Minutes takes over the Tomlin house to do a story on Zan. Despite the disruption to Zan's routine, the filming goes well. Greg Jaworski returns to Berkeley with boxes of data.

Ben returns to school, hoping to reconnect with Jennifer, but David finds Ben's Project Jen journal, mortifying Ben. The Tomlins introduce Zan to a new research assistant, but when she does not respond to Zan's signs, Zan attacks her.
