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.

Relationships

 * -|Abigail Griffin =

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.
