User blog comment:Xxkiiroxx/"Marco is Alive" Theory/@comment-10733658-20141004052737/@comment-25448721-20141004054517

Thanks! And yeah, true! But there are just some things you can't help but noticing, especially for hardcore fans of Marco xD

Ultimately though, I feel that all of this is up to Isayama's imagination, he could change things up whenever he wants. I doubt he has a plan that's set in stone.

About derailing Jean's character, there are some fans imagining that if Marco was a Titan shifter (which actually isn't an uncommon theory), it would be really sad if Jean is the one who kills him.
