Clarke doesn't hate you, Abby. She's just - she's just strong-willed... like her mom. You gave her that. That's how you're protecting her. And that's what will keep her alive on the ground.

Throughout the Series

In Pilot, Jackson and Abby theorize that the two Delinquents who died were killed on impact because their tiles went black at the same time they lost communication. Jackson later helps Abby operate on the Chancellor after he had been shot, but Jackson refuses to break the law by giving the Chancellor more anesthesia, even when it had to be done.

In Earth Skills, Jackson and Abby discuss a possible signal that can be sent down to the Delinquents, but Jackson states it wouldn't work because the wristbands weren't designed to receive data. Raven reveals to Jackson and Abby that the Delinquents are taking off their wristbands, and Jackson, who is shocked by this, asks why they would do something so reckless, and Abby says it's because they told them not to.

In Murphy's Law, Jackson tries his best to comfort Abby after he finds out that Clarke's wristband signal went out, but Abby refuses to believe the worst has happened, and orders Jackson to get her an analysis of Clarke's vital signs from the past two days. Jackson later warns Abby when Kane and his guards are coming for her.

Abby is determined to save her, but Jackson wonders what she is saving the woman for, since the Ark is running out of air and they will all be dead within a couple of days. Abby breaks down saying that Clarke hates her because she turned in her husband, Clarke's dad, and got him executed. Jackson comforts her by saying that Clarke doesn't hate her she is just strong willed, and it's that trait that will keep her alive on the ground.

In We Are Grounders (Part 2), When the Ark is brought down to Earth, Jackson is on one of the stations that makes it to the ground.

In Wanheda (Part 1), Jackson rushes to the gate of Arkadia to greet an injured Jasper and immediately takes him to Medical. Jackson is later seen chasing Jasper down the halls, begging him to stop because he hasn't been cleared from Medical, but Abby sees this and releases him, making him promise to come back in the morning for a checkup. Jackson complains about the twelve waiting patients, four of which who are waiting for contraceptive implant removals.

In Wanheda (Part 2), Lincoln and Octavia bring a dying Nyko to Jackson and Abby. A large amount of blood loss and deep gash requires Nyko to need a blood transfusion. Jackson takes Nyko's blood but realizes that it's Rh null, so none of the Octavia can't give some of her blood to him because Abby says Rh null can only take Rh null. Lincoln offers up some of his blood for Nyko and Jackson takes a sample of Lincoln's blood type, however, he soon finds out that Lincoln's blood type isn't Rh null either. Jackson says there is another option but Abby silences him before he can say what it is. Lincoln wonders what Jackson is talking about, and Jackson suggests Mount Weather since it will have the blood supply necessary for the transfusion. Abby scolds him, pointing out that the Mountain Men bled thousands of Grounders to death so they can't take him there. When Lincoln is asked what he thinks about the idea, Lincoln says that they have to save Nyko, despite knowing that there is a risk that the tensions between the Sky People and Woods Clan will increase if they take Nyko there. Jackson, Abby, Octavia, and Lincoln prepare to transport Nyko to the Mountain. Once Jackson and Abby save Nyko's life, Jackson points out all of the good that Mount Weather could do for both groups of people. Nyko agrees by saying that he and Lincoln can change the minds of their people and that it's not the places that are evil; it's the people. Abby gives Jackson permission to open Mount Weather back up, and he is greatly pleased by this.

In Sanctum, he is chosen to go a mission to explore the new world as a part of Expedition 1. Upon landing on the ground, the group is thrilled to find that the air is breathable and the radiation levels are good. He mostly spends his time alongside his boyfriend Nathan Miller while they are exploring. Later, sitting around the campfire he and Nathan relax and talk about their new status as aliens, while they are observing a bug that they caught up in a jar.

As an eclipse approaches, the group notices that a bug they had captured in a jar is becoming extremely violent. Suddenly, a huge swarm of bugs approaches them at high speed. They run to seek shelter while using fire flares to scare off the bugs. Soon, they reach an electric tower with a radiation fence which kills the bugs. Shaw accidentally runs through the electric barrier and gets burned by the radiation. Clarke notices that they are radiation-type shockers and she can go through them because she has nightblood. She goes through the barriers and disables the tower temporarily to let the rest of the group get inside.

While Miller and Jackson talking to each other sitting on the stairs they get interrupted by Murphy yelling at something. Miller then shouts that someone stole their transport ship and it's now flying away. A couple moments later, Emori starts attacking Murphy out of nowhere. The group quickly comes to save him and notices that Emori turned violent during the eclipse in a manner similar to what's depicted in the "Red Sun Rising" book.

In The Gospel of Josephine, he is arguing with Abby about her obsession with saving Kane since it's impossible to perform a successful surgery before Kane dies. Josephine interrupts them and begins to help Abby, asking Eric to give them some time.

Later, they again are talking about upcoming surgery. He is worried about the fact that Abby haven't slept in 2 days and spends all her time with books, replacing the pills with them. Abby says she needs to bring Kane back because out of all of them, he is the only good person who deserves to live. She mention that they both stand with blodreina which makes them a war criminals.

In The Old Man and the Anomaly, he with the others is sitting in the Tavern and discussing the plan to bring back Clarke and get out Josephine. Madi suggests just to kill all the Primes but the groups decides to do it in a less bloody way.

Then Emori comes in, she firslty asks for a Shock Collar, but then realizes that she can't just stay away and tells that Clarke will be killed now. Together they begin working on a new plan. When Emori makes Josephine to get to the shield, Eric and Nathan are ready to go to them. However Madi kills Miranda and it forces Russell to start the alarm and capture Earth people. Jackson, Miller, Emori, Echo, Murhpy and Madi get locked up.


Jackson, like most everyone on the Ark, is a law abiding citizen. He expresses no desire to break the rules, as shown when he refuses to give the Chancellor more anesthesia. Jackson will even voice his opinion when someone else tries to break the rules. However, Jackson also cares for his friend Abigail Griffin and shows a high level of devotion to her.

He seems to have a strong moral compass and does not waver from his ideals and morals.

Physical Appearance

Jackson has an olive complexion, dark brown eyes, and black hair. He wears simple clothing. Jackson has a thin build. He seems to be of an Indian descent.

In Season 5, after the 6 years and 7 days jump, he has a beard.


Abigail Griffin

On the Ark, Abigail is a good friend and co-worker of Jackson's. Although they do not always see eye to eye, the two generally get along very well. Jackson listens to Abby and respects her, even when they disagree on the course of action to take, such as in the Pilot when Abigail breaks the law to save the life of Chancellor Thelonious Jaha. Jackson seems to trust Abigail more than any other Council member, including the Chancellor. When Marcus Kane searches for Abby, suspecting she is doing something illegal with Raven Reyes, Jackson calls her to warn her allowing Raven to have enough time to launch the repaired escape pod while Abby stays on the Ark. On what they think are their last few days to live (We Are Grounders (Part 1)), Abby and Jackson are seen together operating on a young girl who was hurt in the bomb blast on Unity Day. When the surgery isn't going well Jackson says they, "never should've opened her back up," Abby fight for the girl's life, but she can't be saved. As the heart monitor goes silent and the child dies on the table Abby says, "I failed," and Jackson tries to comfort her while she cries, telling her Clarke doesn't hate her and is just "strong-willed like her mom." He then sends her out of the operating room.
