Okay unlike a lot of people I loved the content of this episode. I don't understand everything without the subs (although I read the summaries so I am a little more informed than usual).
But it's like no I didn't see any of this coming but if I look back it was all set up well. Not to mention I am not going to judge this turn of events until we see how everything unfolds. This was the start of the final novel, so of course it was going to be a game changer.
And like others I am not worried about my ship Ringo X Shouma at all. I don't think the ending is going to be
My only disappoint is the ending of the 2nd novel with Ringo & Shouma seems to have come to nothing in the anime (sigh).
As for Kanba
The only thing I didn't like about this episode was the animation was awful. Character designs were totally off and in at least one scene there was barely any movement
edit: Nina Wolken, Kanba was 13 not 8 when they found out their parents were terrorists. It happened 3 years prior to the start of the story.
