Not much in the way of surprises here, but when what you're expecting is what I was expecting from Zankyou no Terror, that's not a bad thing.
another Oedipal riddle, another bomb and another battle of wits this week, and normally I'd be pretty worried that the series might be falling into a weekly pattern. I don't want to see this repeating itself over and over, but I'm not overly concerned because my sense is that this is a transitional episode, one which brings the setup phase of the story to a close and ushers in the next. If I'm wrong it could be a bit of a problem (and I would feel better knowing who's doing the writing) but I don't think I am. We'll know one way or the other next week.
Arahabaki and and the Shirahige Jinja next to which they've hidden their latest bomb, and the fact that the police have connected it to the Plutonium theft, the lads are genuinely pleased. One might posit that they're simply eager to get into a fun battle of wits with a worthy opponent, but I think it's more likely that they were trolling for someone smart enough to help them expose something the government is presumably extremely anxious to avoid seeing exposed.
leaving the streets lonely and desolate for the child Shibasaki, as well as his low-key yet chilling depiction of the horrors the young Oedipus endured - left to die by his father in the forest with a nail through his foot. It's no coincidence that Arata and Touji chose him as the centerpiece of their first two riddles, and their story promises to reveal dark and terrible details with each passing week. Let's hope it ends more happily than the original did.
