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 the 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 intending to rape her. Jason, hearing the commotion, killed the bandit with an arrow. After that, he successfully gained the group's trust and traveled with them to Chicago to locate his primary target, Miles Matheson.
They reached Chicago the next morning and entered a bar/hotel. The group took a seat at the bar and Charlie asked the bartender where Miles was. The bartender said he didn't know Miles. After Charlie explained the events that led them to Chicago, the bartender asked her to follow him to the backroom. Jason, who did not want Charlie to leave his sight, took out a knife and pointed it at the bartender. The bartender easily took the knife out of Jason's hand and forced it against his throat. The bartender explained that Charlie was his niece and he didn't know Jason. With that revealed, Walker had completed half his mission. Now he just needed a way to get to a nearby militia settlement and lead them there to arrest Miles.
After Charlie and Miles spoke in the backroom for a few minutes, Charlie came back in tears and said they had to leave. Walker angrily walked up to Miles with the knife and demanded to know what he did to Charlie. Miles once again took the knife out of Jason's hand and pulled down his sleeve. His branded militia insignia was revealed to the group, eliminating his cover.
Jason took out his bow and arrows and backed out of the bar. He tracked down a militia squad not far from the bar and told them he had located Miles Matheson in Chicago and would lead them to him. They arrived at the bar, where Miles was drinking in the back room. Jason said he had orders to arrest Miles in order to obtain information about The Blackout. When some men moved close to Miles to apprehend him, he fought them off. He mostly used hand-to-hand combat to kill almost half of the squad. However, he eventually got surrounded, but thanks to the timely arrival of Charlie, Maggie, and Aaron, he was saved and they fought the militia together. He knew the squad was going to be wiped out and decided to save his own life and retreat. On his way out of the bar, he saw Charlie being beaten by a militia soldier. He hurried over and whacked the soldier on the head with his bow, causing him to go unconscious, he then ran off.
Jason followed Miles and Charlie Matheson, Aaron, and Maggie for a day. He crept behind desolate trains in a train yard as the group continued to follow the tracks.
He tracked Charlie when she left Aaron and Maggie behind to look for Miles, who ran off to find Nora. When she realized she was being followed, she faked being hurt by jumping off a wall next to an abandoned interstate where he then offered to help her. She refused his help, but he hurried to help her anyway. When he got close enough, she handcuffed him to a utility pole and questioned him as to what he was doing. Upset that he was using her group to try to flush out her uncle, Charlie turned to go. As she left, he revealed his name was not Nate Walker.
Jason tracked Charlie, Miles, Nora, Aaron, and Maggie into an amusement park. Miles sensed him nearby, and the two got into a fistfight. Charlie pushed Jason away from Miles and suggested taking him prisoner to try and get information on Danny, instead of letting Miles kill him. Jason was handcuffed again and brought along with the group.
Later, when Charlie was kidnapped by the man who kept the dogs, he helped Miles find her and rescue her, killing the man.
Leaving The Militia
After Danny's family escaped from Monroe in Philadelphia, Jason and his father tracked them to a rebel camp. As Tom was getting ready to inform Monroe of the rebel location, Jason tried to stop them by saying this is not what he signed up for. Tom and Jason fought it out with Tom getting the best of him. Instead of killing him, Tom told his son to never come home again.
Jason found Charlie and warned her of the impending attack. Although she was grateful for the warning, she told him to leave.
After joining the Rebellion, Jason tried to help Charlie get Dr. Stephen Camp back to his family. His father continued to push his son farther and farther away from ever having any respect for him. Soon after trying to help the Dr. get back to his family, Jason became even more disgusted with his father, and he walked away from his father after Tom tried to make his own son shot him; which he did not. Charlie followed Jason and they attempted to go north, but before they could, the Rebels were attacked by Monroe's Militia out of nowhere. Jason was beaten up badly. Tom went to his rescue, saying that he had done every bad thing in the good book, but that he drew the line when it came to seeing his own son die alone. Jason was taken to a hospital in Georgia and Charlie stayed next to his bed waiting for him to wake up. When Jason woke, he saw Charlie and began to apologize for not saving her. Jason touched her face with his hand and Charlie moved in to kiss him on the lips, and he kissed her back.
Jason got off the Helicopter with his Father and the rest of the Group. Later, Neville and Jason went to explode an amplifier in Monroe's encampment. Then Neville and Jason fought the Monroe Militia, however when Miles, Charlie, Nora and Aron got in, the tower door shut out Jason and Neville before they could get in.
Texas and Death
Jason and his father joined the Patriots in hopes of eventually murdering their leader in revenge for Julia, whom they believed had died in Atlanta. Jason was sent to a reeducation center created by the Patriots and was brainwashed into an assassin. When Tom found Jason, he successfully brought him back to his right state of mind. After their plan was found out by the Patriots, Julia was captured, and Neville and Jason hunted down Monroe in hopes of killing him in exchange for Julia's life. However, Jason's reprogramming was not completely gone, as he was eventually forced to reveal Tom's plan. When Neville told Jason to suck it up and fight, Jason ran off. Furious that The Patriots were brainwashing young kids just like they did to him, and then discovering that The Patriots were planning on assassinating President Carver, he along with Miles, Bass, Charlie, and Conner made their way to Austin to thwart it. However, Jason's programming kicked in again and was used as Plan B to assassinate President Carver. When Charlie found Jason, he attacked her, not being in the right state of mind. Charlie stabbed Jason in the leg in an attempt to stop him, but he attempted to stab her. Charlie shot him in self defense and Jason died in her arms.
He was known to try and do the right thing, even against his father's wishes, and switched sides many times. He had a weakness for Charlie and many times came to her rescue.
