Marcus Kane

Marcus Kane is a major character in the first, second, and third seasons. He is portrayed by starring cast member Henry Ian Cusick and debuts in the season premiere.

Kane was a Council member on The Ark and Chancellor of Camp Jaha before his departure from the camp. Kane was on the Council when they decided to send the 100 to earth and when they decided to cull 320 Ark citizens to save oxygen.

Once the Ark came to earth, Kane helped establish Camp Jaha as its first Chancellor before passing along the Chancellorship to Abigail Griffin in order to seek peace with the Grounders. After his return to Camp Jaha, he often sided with Clarke Griffin and worked as an emissary between the Sky People and the Grounders.

Early Life
Not much is known about Kane's early life, only that he was born on the Ark to Vera Kane and at some point was made a member of The Council on the Ark prior to the Pilot.

Physical Appearance
Kane is a tall man in his forties with wavy dark brown hair and eyes, and tan skin. He appears to have an authoritative presence.

Personality
Kane is a pragmatic individual, cold and willing to do whatever he deems necessary to "save the human race" for the beginning of the series. Rather than seeing himself as overly dedicated or mean, he saw others as lacking what it takes to do what needs to be done. He cared little for the lives of individuals, only for the idea of the human race as a whole.

Following the events of The Culling, however, Kane is filled with regret and remorse over his actions, depicted over the course of the next season and a half. After his failed attempts at leadership, he learns to place trust in his leaders. Marcus eventually ends up being very loyal to those above him. On Earth, he supports and trusts Clarke as his leader.

After Section 17, Marcus becomes very selfless and willing to sacrifice himself. He stands up and begins to offer to leave himself behind on The Ark to allow the remaining humans to make it to Earth in We Are Grounders (Part 2), though Thelonious Jaha is already launching the ship before Marcus can do as such. In Fog of War, when Jaha and Marcus are informed they must kill the other to stop the bloodshed, Marcus never considers hurting Jaha an option. When Thelonious refuses to kill Marcus, Kane cuts his own wrist deeply with the knife.

Kane often thinks logically rather than emotionally, though he is no longer "cold". What he believes is right is more often than not helpful for more people, such as his suggestion to turn in Finn to the The Grounders (Earth) and establish safety for the remaining Sky People, though he is written off as unfeeling for his objective approach.

Relationships

Callie Cartwig
Callie Cartwig and Kane appeared to share some kind of romantic connection and Kane seemed to care about her somewhat. He says to her he cannot compromise for anything, "even her" in the Pilot. She has since died.


 * -|Thelonious Jaha =

Thelonious Jaha
Thelonious Jaha appears to be on friendly terms with Kane, despite accusing him of shooting him in the Pilot. Jaha accuses Kane outright of trying to take his place, learning Kane would execute Abigail for saving him. Kane has appeared to care about Jaha, advising him not to take his own life with the 320 whose lives will be taken in the Culling. Jaha knows Kane well enough to recognize that he is intoxicated in Contents Under Pressure. When Jaha stays behind as the Ark descends to Earth Kane stays in contact and is seen asking about him multiple times later on Earth. When they are both held captive by the Grounders in Fog of War, Marcus and Jaha appear to be glad to see one another. They both refuse to kill one another and eventually Kane tells Jaha to kill him and ultimately cuts his own arm when Jaha refuses to comply, to which Jaha is visibly distressed. Marcus, despite being a firm believer of punishments (his sentence of 10 shocklashes to Abby in Reapercussions), insisted that Thelonious be pardoned for treason in Remember Me.


 * -|Abby Griffin =

Abby Griffin
On the Ark, Abigail Griffin and Kane constantly had opposing views. Kane saw Abigail as a threat to his goals and frequently had her arrested and even almost floated her once due to his strict rule-following and her bending of the rules. Later, in The Calm, he seems to start caring for Abby, saving her life when he is exploring the other deck to look for survivors. On Earth, Marcus was the first person to follow Abby out of the Ark ship once it landed.

In The 48 they go out looking for the The Camp of the Delinquents and Clarke together. When Abby gives guns to the Delinquents to help them escape and look for Clarke and the others, Marcus sentences her to shock-lashing in Reapercussions before passing along the Chancellorship to Abby. In Resurrection, Abby finds Marcus trapped under rubble after the missile on Tondc, pulling on a piece of metal to make noise and she grabs his hand to stop him. Abby tries to help him and he tells her to leave him and go find Clarke until Abby explains that Clarke got out as she already knew about the attack. When rocks fall down and trap them both further, they talk about how their actions on the Ark have influenced Clarke and the sins they have to answer for. Later, after they are captured by Mount Weather and Abby has her bone marrow extracted, they return to Camp Jaha, holding hands.


 * -|Vera Kane =

Vera Kane was Marcus' mother. They had a strained and distant relationship, although he began to let her in again after he told her he didn't know who he was anymore. Not soon after however he was again distant with her until on Unity Day she is a victim of the bombing and as she is dying Marcus recites the traveler's blessing he learned from her in his childhood. When he arrives on Earth he plants the Eden Tree his mother had taken care of on the Ark.
