Jason was born in 2005. The son of Tom and Julie Neville, he was 7 years old when the Blackout occurred. On the day of the Blackout, he greeted his father as he came home from work. That night, he was watching his father punch a punching bag. When his father began to teach him, the power went out. Tom told his son only to punch the bag, and not people.
Six weeks after the blackout, a neighbor breaks into the Neville home in Allentown, Pennsylvania. Jason runs downstairs and witnesses his father beat the man to death.
Fifteen years after the blackout, Jason Neville is a member of militia, working for his father Capt. Tom Neville. He is given one simple order: Pretend to be a survivor of The Blackout and make friends with Charlie Matheson and her group, keep deceiving them until they locate what they are searching for, Miles Matheson, who seems to be the only one now who has information about The Blackout since his brother Ben was killed. So he stages it near a waterfall and begins the act. He practice fires his bow and arrow as Charlie sneaks up behind and watches him. Jason indicates that he knows she is there. Charlie says she is just going to get some water for her canteen. They go their separate ways for now. Later that night, the group was being mugged by three bandits. One of the thugs was dragging Charlie to the cockpit to potentially rape her. Jason, hearing the commotion, kills the bandit with an arrow. After that, he had successfully gained the groups trust and travels with them to Chicago to locate his primary target, Miles Matheson.
They reach Chicago the next morning and enter a bar/hotel. The group takes a seat at the bar and Charlie asks the bartender where Miles is. The bartender says he doesn't know Miles. After Charlie explains of the events that led them to Chicago, the bartender asks Charlie to follow him to the backroom. Jason, who does not want Charlie to leave his sight, takes out a knife and points it at the bartender. The bartender easily takes the knife out of Jason's hand and forces it against his throat. The bartender explains that Charlie was his niece and he doesn't know him. With that revealed, Walker has now completed half his mission. Now he just needed a way to get to a nearby militia settlement and lead them here to arrestMiles. After Charlie and Miles speak in the backroom for a few minutes, Charlie comes back in tears and says they have to leave. Walker angrily walks up to Miles with the knife and demands to know what he did to Charlie. Miles, once again, takes the knife out of Miles hand and pulls down his sleeve. His branded militia insignia was now revealed to the group, eliminating his cover. Jason takes out his bow and arrows and backs out of the bar.
He tracks down a militia squad not far from the bar and tells them he has located Miles Matheson in Chicago and says he will lead them there. They arrive at the bar, where Miles is drinking in the backroom. Jason says he has orders to arrest Miles in order to obtain information about The Blackout. When some men move close to Miles to apprehend him, he fights them off. He mostly uses hand-to-hand combat to kill almost half of the squad. However, he eventually gets surrounded, but thanks to the timely arrival of Charlie, Maggie, and Aaron, he is saved and they fight the militia together. He knew the squad was going to be wiped out and decides to save his own life and retreat. On his way out of the bar, he sees Charlie being beaten by a militia soldier. He hurries over and wacks the soldier on the head with his bow, causing him to go unconscious, he then runs off.
Jason has been following Miles and Charlie Matheson, Aaron, and Maggie for a day. He sneaks behind desolate trains in a train yard as the group continues to follow the tracks.
He tracks Charlie when she leaves Aaron and Maggie behind to look for Miles, who ran off to find Nora. When she realizes she is being followed, she fakes being hurt by jumping off a wall next to an abandoned interstate where he then offered to help her. She refuses his help, but he hurries to help her anyway. When he gets close enough, she handcuffs him to a utility pole and questions him as to what he's doing. Upset that he was using her group to try to flush out her uncle, Charlie turns to go. As she leaves, he reveals his name is not Nate Walker.
Jason tracks Charlie, Miles, Nora, Aaron, and Maggie into an amusement park. Miles senses him nearby, and the two get into a fistfight. Charlie pushes Jason away from Miles and suggests taking Jason as prisoner to try and get information on Danny, instead of letting Miles kill him. Jason is then handcuffed again and is brought along with the group.
Later, when Charlie is kidnapped by the man who kept the dogs, he helps Miles find her and rescue her, killing the man.
