Shawn Gillmer

In Watch the Thrones, he is seen at the Mount Weather memorial. When Lincoln enters the room Shawn yells at him, saying that he is a Grounder, and shouldn't be there. A riot breaks out, and during the commotion, Shawn takes a rock and throws it at Lincoln's head, injuring him. Later, Shawn is among Pike's group of followers who try to leave Arkadia armed with weapons to attack the Grounder army outside. When Lincoln and a few other Ark Guards try to stop them Shawn points a gun at Lincoln's head, but is easily overpowered. Chancellor Griffin and Kane arrive with more guards and arrest Shawn and the others. The next day while in jail, Kane informs Pike that he has been elected Chancellor. Pike frees himself, Shawn and the others.

In Hakeldama, Shawn greets Jaha at the entrance of Arkadia, but refuses to let Otan enter. Gillmer tries to take the metal box from Otan who refuses to give it up and he is killed in the process with Gillmer claiming Otan tried to reach for his gun. Later, when Pike orders the sick Grounders to be taken off medication and arrested, Lincoln beats Gillmer to the ground.

In Bitter Harvest, he is seen with Hannah and a few others collecting soil samples at the river bed to take back to Arkadia. Eventually, the group spots a Grounder child. Though harmless, Gillmer is tempted to shoot the child, but Hannah tells him to hold off. Hannah then gives Gillmer the signal, and he tries to shot the child, but misses. They chase the child but he ultimately escapes with Octavia's help.

In Fallen, he is killed by Octavia, after Pike is taken prisoner by Grounder warriors.

Charles Pike Edit

Shawn and Pike appeared to have a good relationship. He was loyal to Pike during his rise to power as the new Chancellor and the war with the Grounders.

Lincoln Edit

Lincoln and Shawn have a very hostile relationship. Most of their encounters have proven to be very violent, with Lincoln easily being able to overpower Shawn.
