Maybe, but apparently there are official "Titans" for each cast member. Or at least the former trainees. I was wondering if these were an example...do I need to talk about gag or omake material in spoilers?
I've feeling that Mikasa is secretly a Titan. I mean look at Annie, Berholt, Reiner, and to lesser extent, Ymir.
makes a lot of sense when you consider the event that brought her and Eren together when they were kids. How else would she be able to leave a crater in her floor and crush the knife handle in her hands?
