Ep 16. Blood Must Have Blood - Part Two

Blood Must Have Blood - Part Two is the final episode of the second season of the post-apocalyptic drama series The 100. After the events of the previous episode, Clarke, Bellamy, Octavia, and Monty have made it inside Mount Weather's control room and are trying to shut down the facility's power supply to free their people. On the other hand, Kane, Indra, and Lincoln are leading a ground attack to divert the attention of the Mountain Men, who are still recovering from a Reaper massacre.

The episode begins with Bellamy taking charge of the mission inside Mount Weather, and he and Clarke devise a plan to destroy the outer walls of the facility to let their people in. However, they realize that they need Raven's technical skills to make it work, so they send Monty to find her while they try to keep Mount Weather's security at bay. Meanwhile, Jasper is still inside Mount Weather, trying to convince Maya's father, Dr. Tsing, to help them by providing them with a key to the missile launcher.

Outside, the attack on the Mountain Men is not going as planned, and the grounders are outnumbered and outgunned. Kane decides to take matters into his own hands and sneaks into Mount Weather to find and rescue the prisoners. He succeeds in freeing them, but he is caught by Cage, the son of Mount Weather's leader, who is determined to keep his people safe at any cost.

Back inside the control room, Bellamy and Clarke manage to destroy the outer walls, but they realize that they have no way to get out before the facility explodes. However, Raven arrives just in time with a solution that involves sacrificing herself to manually detonate the missiles. Bellamy tries to stop her, but she reminds him that it's their only option to save their people. Raven's sacrifice allows Clarke, Bellamy, Octavia, and Monty to escape Mount Weather and reunite with the others.

The episode's climax takes place outside Mount Weather, where the Mountain Men have launched an attack on the grounders and the exiles. Clarke realizes that their only option is to use the missile launcher to destroy the Mountain Men and put an end to their threat once and for all. While the others keep the Mountain Men at bay, Clarke and Bellamy make their way to the launcher and manage to fire it just in time, taking out Mount Weather and killing all of its inhabitants.

The aftermath of the battle sees the survivors starting to rebuild their lives and their relationships. Clarke decides to leave the camp and take some time to herself, while Bellamy starts to take a leadership role among the exiles. The final moments of the episode hint at new dangers on the horizon, as a group of Grounders appear on the scene, led by a mysterious figure in a red cloak.

Blood Must Have Blood - Part Two is a fitting conclusion to the second season of The 100, tying up loose ends and setting up new conflicts for the future. The episode is action-packed and emotional, featuring some of the show's best performances and most memorable moments. With its compelling characters and bold storytelling, The 100 continues to be one of the most exciting and thought-provoking series on television.
