Why Did Ymir Go Back with Reiner?

First, Ymir agrees to go along with Reiner and Bertholt on the promise that they’ll help her rescue Historia from the conflict brewing between the walled world and the forces outside. Then, she realizes that Historia is actually nearby already and forces Reiner and Bertholt to linger in order to grab her along.

Does Ymir return?

Ymir didn’t have an easy life, and that’s putting it mildly. She hid her true identity until she needed to protect Christa, and after that she risked her life over and over again for her. But in the end, she chose to leave with Reiner and Bertholdt and not return with Eren and Christa.

Ymir knew Christa’s real identity much earlier than the main characters, and one of the reasons for her attachment to Christa seems to be Christa’s royal blood. Although Ymir is a Titan herself, the reason for her attachment to Christa seems to be not only the fact that she is of royal blood.

Who ate Ymir?

Turning into a Pure Titan, Galliard consumes Ymir and gains the power of the Titans. He inherits Ymir’s memories and understands her history and motives, but he sees nothing from the memories of his brother. Four years after the Warriors’ return, Galliard is present at the battle of Fort Slava.
