Continuing from last episode, Araragi and Hanekawa proceeds to figuring out the case of Oikura's mother. I really like the whole detective aspect of this arc and I wa very satisfied the way they figure out the truth. That said, it is an unfortunate truth even Araragi hestitates to tell her but to me at least not too unfortunate that I thought. Regardless, glad this arc ended, I like how this arc is one of the arcs with the least supernatural aspects but focused more on the past of Araragi.
