So… a while ago during the one of my usual readthroughs, I noticed something in Chapter 50 which I’ve been meaning to talk about.
When Eren first uses the Coordinate, they are at a pretty desperate situation like Levi later says. Mikasa is hurt and can’t fight, Eren doesn’t have his 3DMG on and is pretty much done at that point, but the thing about the 3DMG is… they’re on a plains land. Sure, they can use the Titans, but that’s not the point I’m trying to make here.
They are literally in the middle of a grass field. Grass. Grass. And then… after Mikasa and Eren run away… there’s this shit right here:
….Wait a second… what the… O_o
Why are trees growing there?! What the hell?! Where tf did those come from?!?!
Okay, this is immediately linked to my theory that Titans are plants but more specifically… this flower/plant thing has been foreshadowed so much at this point, that I’m betting my money on the theory that the Source of all Organic Material is a tree/plant of some sort. Because 1) @falcon94ssy ‘s analysis, including the constant talks about bloodlines like here:
The flowers in Eren’s dream, the flowers inside the Titan in Episode 9… there are references everywhere. Titans only moving during sunlight and regenerating limbs?
Oh and 2) Isayama REALLY likes Norse mythology. It wouldn’t surprise me if the World Tree was the source of all organic material at this point.
Eren using the Coordinate, aka the direct connection to the source seems to have made those trees grow. Now this may just be scenery artwork but like I said, you don’t see small trees growing around the main characters on a pure field of fucking grass. This has been my analysis of this. Now hurry up Isayama.
