Carl Emerson

Carl Emerson is a minor character that appears in Season Two of the 100. He's a loyal guard that works at Mount Weather. He can be recognized by his various radiation burn marks. He acts as Cage's "right hand man", always remaining loyal to his President and always following orders. After Clarke kills Dante Wallace and then threatens to irradiate level 5 of Mount Weather with radiation, Cage sends Emerson to kill Clarke, Bellamy and Monty. Emerson plans to blow open the door of the control room and kill the trio, but after Clarke and Bellamy irradiate level 5 and kill everyone in Mount Weather, Emerson disappears. Because of his former immunity to radiation, the radiation breach doesn't affect him, and he remains the sole survivor from Mount Weather.

Early Life
Nothing is known about Carl's early life. He was born and lived in Mount Weather until after he was given immunity to the radiation and fled Mount Weather during the irradiation.

Throughout The Series
In Remember Me, he is seen entering the control room in Mount Weather alongside Cage Wallace. When they are about to enter they are stopped by another guard who says that there is a check up for contamination in the room. The masked man checking the room walks out, and says the room is all clear. When the man is about to leave, Emerson says he forgot to put in the results on the clipboard. The man walks up and fills it out, but from what Emerson reads it says that the room is not safe. When the man runs away, Emerson catches him, unmasks him and knocks him out, revealing to be the delinquent Monty.

In Coup de Grâce, Carl is hiding in the woods, along with another person from Mount Weather. When they see Clarke, along with Abby and other Grounders pass by in the distance, his friend, who is equipped with a sniper rifle, claims that he can make that shot. His aim hovers above Clarke but he doesn't shoot. Carl and his friend observe as they stop on the road, but Carl's friend is then shot with an arrow on the neck, causing him to accidentally fire and strike a Grounder. Carl is shocked and tries to run, but immediately finds himself at the mercy of Grounders. His garments that protect him from the radiation are sliced open, and he begins to succumb to the radiation. Clarke however, steps in, believing that it's best to save his life with a clothing patch.

Carl is saved and taken back to the camp. He's kept inside a pressurized chamber, courtesy of Raven, which allows him to take off his protective clothing. After a while, he wakes up and is questioned by Marcus, Abby, Clarke, and Thelonious. However, despite the fact that they saved his life, he doesn't help them in any way and the only thing he says is his name and his occupation.

Later, Clarke forces Carl into dressing his protective clothing and takes him outside. She's followed by a mob of Grounders, but on the way is stopped by Abby and Marcus, who are against the idea of freeing Carl. Clarke manages to convince them, and tells Carl a message that he must pass onto his leader. She then says, "It takes eight hours to reach Mount Weather", Clarke empties his oxygen reserve a little bit. "You're gonna make it in six.". Carl doesn't waste and time and sprints back to Mount Weather.

In Rubicon, Carl is then seen running madly through a field. Once he's near Mount Weather, he succumbs to fatigue and drops to the ground. Cage then appears, not wearing any protective clothing, and he appears to be resistant to the radiation. Carl remarks on this and Cage takes Carl back inside Mount Weather.

Carl is seen multiple times later during the episode, along with other guards and following Cage. He's the one who shoots the missile towards Tondc.

In Resurrection, he is takes part in taking down the delinquents barricaded room. However, when the delinquents pretend to be knocked out, they all wake up and start slaughtering the Mountain Men, with Carl escaping. Carl is later seen with Cage breaching the room again, however at that point the delinquents had all suddenly vanished. Cage then orders Carl and the others to search for them.

In Bodyguard of Lies, Carl is seen alongside Cage in Mount Weather's control room. Emerson updates page on every detail about the grounders, as well as the status of the delinquents. Emerson is eventually seen listening in on Bellamy Blake a mole sent in from the Sky People, as he panics to his comrades how their plan to turn off the Acid Fog did not work. When Cage asks if the fog deploy was successful however, Emerson says there is no sign of the fog. Cage freaking out yells at everyone asking what else they can do, but Emerson and the rest are speechless.

In Blood Must Have Blood (Part 1), he is seen in the control room aiding Cage with handling the grounders. Carl and Cage work desperately to make sure the army does not breach their main door. It is presumed Carl was with the ground unit who fought against the grounders, as he was captured by the grounders. When Clarke attempts to attack Mount Weather, Lexa says to stop and brings forward Carl. Lexa says that she is trying to save her people. Suddenly dozens of grounders walk out and Carl is set free, implying that a deal was made with the grounders and mountain men in order to stop the war. Carl then freely walks right back into Mount Weather.

In Blood Must Have Blood (Part 2), he is seen the in the dining room in Mount Weather updating Cage on the status of the delinquents. Emerson eventually receives a call on the walkie talkie he has. Clarke is on the other end, and Emerson hands it to Cage. Cage then orders Emerson to head to the control room and burst down the door, in order to kill Clarke.

When he reaches the control room, Emerson makes many attempts to break down the door. When he is unsuccessful, but he places charges to explode the door. However, as soon as the alarm in Mount Weather goes, Emerson immediately knows that radiation has been leaked and every Mountain Man will die soon. Emerson then runs off, leaving what happens to him after unknown.
