"Unity Day" arrives where the joining of the orbiting space stations is celebrated. As the ground celebrates, they find their video link interrupted when a bomb explodes during the ceremony on the Ark. Six people are killed, including Kane's mother. Diana engineers a mutiny in order to take the first drop ship, principally for the worker class of the ark. Abby is trapped on board. As the ship launches, it was not fully disconnected from the Ark's main systems, causing massive damage and an Ark-wide power outage. On the ground, Finn is able to arrange a meeting with the local grounder leader through Lincoln in an effort to live in peace. Clarke is requested to represent the group, and goes to the meeting, first recruiting Bellamy to secretly follow with guns as backup protection. During the meeting, the leader Anya accuses Clarke's group of acts of war, including burning down a village (due to the flare rockets) and capturing Lincoln. Clarke tries to convince Anya to live in peace, including mentioning the superior technology of the ark, but Anya is not fazed. Jasper, who came along with Bellamy and Raven to protect Clarke, notices a grounder party in the trees with weapons trained on Clarke. He opens fire killing several. Lincoln is shot with an arrow while protecting Octavia. The group rushes back to the protection of their walls. That night, Clarke and Bellamy notice the dropship descending. It comes in too fast with no parachute, violently crashing in the distance much to Clarke's horror.
