Ryan gathers the team and tells them that Anna is lying about the vitamins. He explains that the visitors are testing something on a large number of humans and probably are planning to restart the program. Ryan says he has a list of visitors he would like to have Erica run in the FBI database. Erica finds a man named Peter Combs who is now a chemist. Ryan suggests they follow him.

Erica tells his therapist who happens to be Valerie that he can't talk to his mom about seeing a visitor and joining the Peace Ambassadors. He says the visitors can do amazing things with their healing centers. Val admits she considered going to the center. Tyler says he knows someone. Meanwhile, Lisa and Anna watch through Tyler's camera jacket as he talks. Lisa says she thinks Tyler is ready now. Anna asks her to invite him to to the ship so she can meet him.

Marcus thanks Chad for reporting on the healing centers. Chad watches as a visitor fixes a woman's arm. Marcus tells Chad they would like him to share their story.

Erica tries to call Tyler, but he ignores her. Ryan calls Erica and informs her that he and Georgie are set to meet with Combs in the parking garage.

Joshua and another visitor named David report to Anna that they have no leads on Dale's death. She orders Joshua to gather suspects. After Joshua is dismissed, David suggests he get off the ship since he is valuable to the column.

Georgie and Ryan ready their guns as Combs goes to his car. Georgie tells Combs he is going to cut him open. Georgie fires as Combs ducks into his car. Comb retrieves a gun and shoots Georgie in the abdomen. As Erica tends to Georgie, Ryan shoots over her and hits Combs. Georgie lies and says Combs just started shooting him first. Erica loads Georgie into Jack's car. As Ryan interrogates him, Combs calls Ryan a traitor then ingests a pill that burns his body. Erica points her gun at Ryan after she figures he is a visitor. Ryan tells Erica that they are on the same side. Since they hear sirens, Ryan asks her what she plans on doing.
