Guys!!! Guys!!! The hooded guy IS Eren!

So, Isayama sometimes places clues in covers of his volumes. Like volume 23 cover has Zeke facing away from other warriors, foreshadowing that he’s going to betray them.

Now, THIS is the cover for volume 17:

Notice what Eren is wearing? Notice his posture and hands in pockets?

Yeah, looks exactly like this:

Need further proof?

Look at what Historia is wearing!

Now, one of these two things on their own could be overlooked. But the scene having Historia wearing the same clothes as in the cover where she’s angled towards Eren AND Eren in that cover wearing the same type of coat (that he doesn’t usually wear) as that hooded picture in the same scene and having the same posture? I don’t know about you, but I am now 100% sure that it was Eren who notified Historia of the danger she was in.
