Christina Warren is a teacher who was nearly killed during her journey on a train by Derek Frost but was saved by her boyfriend Sean Fentress, whose body is actually possessed by a Colter Stevens from an alternate future timeline.


Stevens awakens on a train in an alternate reality created by the Source Code. He is unaware of how he was put there or why. The first person he interacts with is Chritina, who is confused as to why her boyfriend "Sean" is acting strange all of a sudden.

With the information he had uncovered from previous trips into the Source Code, Stevens was able to defuse the bomb and capture Frost before he could destroy the train. Frost was arrested by the police and the people on the train were saved. Stevens and Christina kissed in the last seconds before the plug was to be pulled at the eight-minute mark. In that instant, Goodwin turned off his life support per his request, but to Stevens' surprise, his mind remained in Sean Fentress' body. He was able to safely leave the train with Christina and the rest of the passengers.

A New RealityEdit

Now in the alternate universe, where the bomb was defused, the alternate version of Goodwin received an email from a now free and assuming the identity of Sean Fentress, Stevens, explaining what has happened and how the Source Code works by connecting (or creating) alternate realities. The alternate version of Goodwin received the letter before she was even aware of the operation or of the bomb that will explode on the train later that day. Stevens asked her to listen to him and consider his requests once her communication began with the Captain Colter Stevens inside the chamber she soon will find out about.
