Throughout the Series Edit
In Contents Under Pressure, Costa aids Jaha in controlling the crowd which is about to attack Kane. Later he is standing sentry during the general assembly in which Jaha reveals the truth about the 100.
When the Ark is brought to the ground Costa was on Mecca Station.
In Ye Who Enter Here, Costa is one of the guards escorting Kane and Acting Chancellor Abigail Griffin to Polis. Once at the city limits of Polis, the group dismount their vehicle and prepare to go ahead on foot once Indra's warriors have rendezvoused with them. Costa hooks a med kit to his belt but is told by Kane that he can't take it into the capital because it came from Mount Weather and would offend the grounders. When in Polis, Costa continues to escort the Chancellor and Kane as well as taking in the sights and talking with the locals.
In Terms and Conditions, Costa is seen at the gates of Arkadia when the two grounder messengers approach. He watches them converse with Pike and Bellamy and hears them issue a warning to the Arkadians that if they try to leave they will die. Costa watches as Bellamy kills both messengers.
In Join or Die, having been chipped by A.L.I.E., Costa is seen in the tower of Polis with another chipped guard when they deliver Abby to Kane (who has been imprisoned in the tower and is unaware that Abby is chipped). Costa and the chipped grounder warrior wait outside the door while Abby tries to get information from Kane regarding the whereabouts of Clarke and the Flame. As soon as Kane sees through the ruse and realises Abby is chipped, Costa and his fellow guard enter the room and seize Kane – Abby orders the guards to put Kane on the cross.
Hauling Kane outside, Costa and several more of A.L.I.E.’s minions hold Kane down and chain him to the crucifixion cross. Costa then stands back as Briggs drives nails through Kane’s wrists and watches as Kane’s cross is heaved upright.
Costa is still keeping watch on Kane when Jaha and Ontari arrive. Jaha offers Kane the chip, but he refuses, so Costa gives Jaha his gun. Jaha threatens to shoot Abby in the head unless Kane takes A.L.I.E.’s chip, and so finally, Kane accepts the key.
After the City of Light has been destroyed, in Echoes, Major Costa brings a group of Sky People to the Flamekeeper's temple to lead them out of Polis through a secret tunnel. He meets Kane and tells him he has 10 guards at the temple entrance and offers to stay in the city. Kane declines his offer and tells Costa to lead the other Sky People back to Arkadia.
In The Tinder Box, Costa listens to David Miller's briefing on the defence of Arkadia from the impending assault of Azgeda. When Clarke arrives and suggests she goes to talk to King Roan, Monty alters her idea in favour of the Arkadians setting up ambush positions on the invading army's path.
When Roan's army attempts to pass through a canyon, Costa and the other Arkadian guards take up ambush positions on top of the adjacent cliffs. After Roan is persuaded to talk privately with Clarke, Costa and the other gunners continue to train their weapons on the Ice Nation army. While they are waiting, Monty radios Costa asking if he knows the whereabouts of Riley, one of the sharpshooters, Costa replies that Riley went to relive himself a short while ago. Monty asks if Riley took his rifle with him: glancing over at Riley's previous position, Costa notes that Riley did indeed take his weapon, but that he left his radio behind.
