Nah I don't think so, some say it's a loop. KILLY found another child with a terminal gene thing and the story repeats I guess until the h7minity is saved.
spoiler alert(?) (in chapter 137) after he gets swallowed and ends up in the paths w zeke , he talks to zeke and then zeke somehow brought some of them alive to help the rest fight the other titans soo he’s still alive :)
Plzzz update
