Episode Title:
The Final Chapters (Part 2)
Episode Description:
Chapter 3 – The Battle of Heaven and Earth: The Scouts and Warriors lands on Eren's rib cage, and incapacitate the Beast Titan realizing that it is just a shell with Zeke nowhere to be found. Before Armin has a chance to transform, he is captured in a Titan's mouth. Suddenly, countless versions of the Nine Titans of the past appear on Eren's back, created by Ymir Fritz to defend him. Just as the Scouts and Warriors are nearly defeated, Annie and Gabi appear on the back of Falco's new flying Jaw Titan. Meanwhile, Armin discovers Zeke in the Paths.
Chapter 4 – A Long Dream: Armin and Zeke have a conversation about the meaning of life and Armin convinces Zeke to share his viewpoint and the two call on the deceased Titan shifters throughout the series to help the alliance. Zeke then materializes on Eren's Titan and allows Levi to kill him, which stops the Rumbling. After Armin is rescued, he uses the power of his Colossal Titan to destroy Eren's Founding Titan, releasing the centipede-like organism, the source of all Titan power, from Eren's nape. Falco flies down to the Liberio refugees, but the reunion between the Warriors and their families is cut short when the source turns the nearby Eldians, including Jean, Connie, and Gabi, into Titans to help defend it. Reiner, Annie, and Pieck engage the Titans and the source to prevent it from reconnecting with Eren while he transforms into the Founding Titan once again to fight Armin, leaving Mikasa and Levi the only ones left who can take Eren down. Jumping off of Falco's back, Levi uses a Thunder Spear to destroy Eren's Titan's mouth exposing his human form within and Mikasa beheads Eren. Ymir is thus freed from the Paths allowing her to pass on, and the Titan powers, along with the source, disappear from the world, turning all the Eldians permanently back into humans.
Final Chapter – Toward the Tree on That Hill: After Eren's death, Armin (and the others) recall a conversation with him prior to his death where he reveals his true motive was to ensure his friends’ statuses were elevated to the saviors of humanity to the rest of the world, alongside giving them the long, fulfilling lives he wanted them to have in a world free of Titans. After mourning their friend, Armin decides to take credit for killing Eren, Mikasa leaves to lay Eren to rest on Paradis, and the Scouts and Warriors are hailed as heroes by the survivors of the Rumbling. Three years later, with eighty percent of humanity decimated, the Jaegerists strengthen Paradis' military to prepare for a potential future attack from the rest of the world, while the remaining Scouts and Warriors become the world's ambassadors for peace negotiations with Paradis. Mikasa buries Eren's head under a tree that he would frequently rest under as a child and continues to visit his grave throughout the rest of her life. Many generations later, a futuristic Paradis is bombed from above and destroyed in a war. Over time, Paradis is reclaimed by the wilderness, and within this wilderness a lone boy and his dog approach the tree Eren is buried at, which has since grown to resemble the original tree that contained the source of the Titans' power.
