*Agrees with everything Heliotropic said*
I think we can take Sera's outburst as confirmation that Mary is momma Akai. I just wonder if Shuu knows though. Conan needs to have a interrogation over stew with Okiya. It seems that Conan lost momma Akai's trust for being careless with the bowtie. Or maybe she was just nervous because the gadget was pretty elite and that freaked her out a bit.
On today's episode of Annoyed Gin gives a short comment on recent plot developments while Vodka drives him around for fun, it doesn't seem like anything very valuable came out of it. Gin bitches about people when they are not around like usual, and the revelation that Haneda Kouji's death connects to a mistake Rum made is not surprising. If anything, I think this explains how Kogoro has avoided more trouble so far. A unneeded celebrity death is not something the BO wants because it can't be kept down and the info barrel keeps springing leaks even decades after the fact. I'd be curious to know if Gin is willing to pressure Amuro for more info on Kogoro, assuming he even knows where Amuro is.
Probably the MIB's cameo was mostly for movie hype. If we are lucky we will get more in depth stuff next chapter, but I suspect it will be another case where Conan spends the first part of chap 1 and the last part of chap 3 mulling over Sera's outburst and trying to put two and two together about Haibara's appearance.
I wish Gosho would show the BO doing other things rather than just driving. Hanging out in a hideout, gun maintenance, drinking, observing deliveries, doing stakeouts, even just walking. Vermouth gets some variety, mostly to take advantage of her sex appeal, but none of the others do. It would be nice if there were some successful crimes to remind us the BO aren't totally incompetent.
