No doubt. So Ymir is dead, after going with Reiner and Bertholdt they took her back to Marley only for her "jaw titan" powers to get passed on. That sucks, I expected a bit more of her I guess.
Really curious what titan research bi-products has to do with the Ackermans. Makes me wonder if they're not even Eldians.
So we've got the original, assault, armored, colossal, beast, female, and jaw titans. We've got Peak with some other titan power, and it's apparently a form she can stay in for long periods of time with the mention of the two weeks bit and forgetting how to walk on two legs. That still leaves one that hasn't been revealed.
