Ok, the music was carrying this episode really hard. And I don't mean that it comes at the expense of other production elements, it's just I have never seen anything quite like this before. It's emotionally moving in ways that you can't just explain. I have seen other shows that have tried doing the same thing before, but it's different here. Nothing prepared me to get engaged this deep on a mini-arc of an anime. Admittedly, I'm out of words to describe what happened in this instance, I can only recommend that you watch it. Undoubtedly one of the most memorable experience I ever had watching a series like this.
