While I'm excited about the development of the boss reveal, Shinichi-Ran being official and BO having a renewed interest in Kudo Shinichi, it is a bummer that Shinichi's daddy took a look at the message and figured out the identity of the boss before his own son did.
Shinichi said it before: this is his investigation and now his OP parents are coming in to do the planning for him. I guess Shinichi's daddy is right: he is way over his head and occasionally bailing him out at critical moments like this one shows that Shinichi isn't ready to take down a international crime syndicate by being in charge in the operation.
I do hope Shinichi finds a moment that allows him to surpass his father later on this series.
