No he didnt transferred it because he didnt need to do it that time as he was not completely beheaded so what he did was to go into Titan form to recover from that injury but the second time he was in his titan form and completely beheaded so thats why I think he did that I mean transferred his...
Yeah but for that you have to do it before your head gets chopped off and he transferred it to his titan not to his body and he gets recovered in his titan form only not outside of it.
What Reiner did was transfer his consciousness to his titan body but Eren is in human form. I don't think he can do that in human form .
Why every body has abandoned the Female titan including Hajime Isayama? She single handedly changed the game last time .
