I thought that this episode was okay. Eren going out of control in Titan form was a bit surprising, but I was more surprised with how he was in a dream-like state seeing how his family was before the Titans attacked all those years ago. It made sense that he would want to think that was reality and just stay there, but it also felt kind of sudden given that there wasn't any sign of that happening before. Granted, we don't know that much about his Titan powers, which also made Mikasa's initial panic even more understandable, but it just seemed a bit too sudden to work as well as I think it could have. Despite Mikasa blushing when that solider told her to save the man that she loves, I don't think that she has romantic feelings for Eren. Given her backstory and the fact that they were raised together for a number of years, it feels more like the love of a family member, but that's just how I feel about it.
Armin was surprisingly calm about the situation and was quite determined to snap Eren out of it. It was cool when that finally worked and the episode was starting to get more exciting, but then it ended. Overall, it was an okay episode. There were some interesting moments, decent bits of action and some good tension. While the pacing for the last couple of episodes have felt like they were stretching things out, at least more was happening in this episode than in the previous one.
