The rumbling stops, the "bones" (I guess it implies the big ass titan) disappear, Mikasa recalls Eren saying he hates her
Gabi and Falco reunite with their families respectively, Pieck meets her had
Annie also goes somewhere to find her dad
After the explosion (137 ending), Armin and Reiner rise up
Another explosion behind them
CT Eren appears, the rumbling titans continue to move
Annie sees her dad, Reiner looks at a vapor-generating spine (not sure which)
The battle is not over yet. Levi asks Mikasa and Pieck to get on Falco and fight
People are titanized by the vapor and, together with "the spine", attack Reiner
Reiner looks at Gabi Jean Connie and motherfucking Karina who are titanized
Pieck and Annie help Reiner
Armin says something to Eren then fight
Mikasa riding Falco in the sky, severe headache
She opens her eyes and sees Eren waking her up (I suppose this part is not the reality)
A short-haired adult Eren lives with her in a random mountain hut, Eren is chopping some wood
But Mikasa is tearing up, then she talks (to the short-haired adult Eren)
Then Mikasa makes a decision
switch to reality
Armin BTFO'd, Reiner Pieck Annie fucked up by the random titans
Mikasa wraps the scarf around her and asks Levi to help her enter Eren's mouth
Levi uses a thunder spear to break CT Eren's teeth, enters Mikasa
Mikasa finds Eren, Eren looks at her
In Mikasa's mind it's an Eren falling asleep next to the aforementioned mountain hut
Mikasa holds Eren's head
switch to reality
Mikasa kisses Eren's head
Founder Ymir is smiling and watching beside them
