I'm going to guess that they did something to the previous Aries, and have possibly done bad things to the other Zodiacs, given the fact that Ziege is reacting in such a way. Children are very truthful about the way they think after all.
I liked the second to last panel. I like the colors. Things are getting pretty tense. I'm just wondering which strong emotion(s) Cretan is feeling right now. I like how everyone is surrounding Ziege right now, like 'PROTECT THE BABY!'
