The finale begins with a flashback to the construction of Paradise. The project manager who oversees the crew, Trent, is a good guy with a big heart who bonds with the workers. When he discovers the excavation is digging up arsenic dust, he brings it to the attention of the architect, who promptly fires Trent.

An identity-stealing man named Trent had a vendetta against Bradford, posing as Eli, a librarian, so he could hide in plain sight. He had attempted to kill the president once before, revealing him to be the man who ended up shooting protagonist Agent Xavier Collins when he'd rushed to protect Bradford, as shown in the first episode.
