So I recently watched Attack on Titan, and loved it. There's certainly a lot of mystery involved all around. Namely...what Are the titans?
Today during a hike, I noticed that in the late evening, ants were really sluggish around their hills. It was then that I realized that their activity is driven by the sun. That made me think about the titans and how they're literally powered by sunlight. I got to wondering about the insects on an evolutionary perspective; they're like machines running on solar power. From their perspective, their anthill is not unlike the human's experience of their walled city in the anime.
Do you suppose there's an intended connection between the titans, humans, and ants?
My mind drifts to something Hangi said to Eren - that the titans they perceive and the titans of actuality may be very different things. I think that this revelation is very important.
