What sucks the most is realizing Eren really did Levi the most dirty, like most of his end game itachi play to bring peace works and all his friends kinda have a chance to have a new life and begin again, but Levi legit gets permentally mamed and has over 10000000 soldiers pstd and like for what, he will never be able to live any type of a normal life again and after Erwin's death and erens betrayal (cause even if eren did do it for the end goal of itachi style big game peace he still would be seen as the true villain for most even those who knew the full situation but) Levi will never trust again or want to really make a relationship with anyone again, dudes legit gonna be thinking for the rest of his life anyone he cares for or trusts is gonna die or betray him. Levi probably has nightmares that this is all some trick still by eren or zeke.
