I feel so sorry for Eren. He trusted them, and then OH MY GOD, turns out they're just a couple of a-holes. He even said he wanted to be as strong as them someday. I was almost crying, really. I'm also disgusted that they took Ymir. Now Ymir's girlfriend who I'd rather call Christa and Eren's foster sister who's creepily obsessed with protecting him are just going to go crazy trying to save them. I also hear in the next episode someone else will become a Titan. I mean, I knew they were a Titan, I just didn't know when they'd discover their power.
