The only thing that slightly interests me in this case is the fact we got Amuro and a highly suspicious Rum candidate along for the ride. Aside from that, ¯\_(ツ)_/¯
I'm hoping it'll go further than what happened in the lastest Sera case, where Conan and Sera only clashed for a liiiiitle bit, and no real results were to be had. Although the sushi guy is behaving too suspicious to my liking already, as if he's a red herring. Unless "he" (both the sushi guy and Aoyama) wants us to think he's a red herring, but isn't. After all, he still fits in with the BO image perfectly with everything he says and does in this chapter, especially the friendliness he displays towards his colleague Bourbon.
