I found this episode to be quite sad on multiple levels. I’m not implying this was a bad episode at all. It’s just the combination of the subject matter with the events in the episode that make it a depressing episode. There were many ways they could have portrayed the main characters of this story. The path they decided on was unique for sure. You could really see the consequences of not knowing how to deal with fear and confusion. Ren’s interest in this specific case might be an indication that his past may be somewhat related to this situation. More specifically, the woman we saw in his flashback a few episodes ago may be his sister. I would be interested in learning more about his past as well as the pasts of the other characters.
