They become sisters

Gigi and Karlie soon had their minds completely emptied. The chairs they were in were different from what Taylor had sat in, as these ones erased Karlie and Gigi's names from their brains as well.

John approached the mindless models, starting with Gigi.

"You are Emma Doe, my athletic tomboy daughter. You are 18 and love playing sports."

Then, Karlie.

"You are Fiona Doe, my sexy slutty daughter. You are 18 and enjoy taking steamy selfies for Instagram."

They woke up and embraced their new lives.
