Actually, they have meet during the ride in the Bell Tree Express (Chapter 819) - Haibara was in some kind of shock because she was thinking about Scarakai and she was terrified about the BO being on the train. I can't really remember the discussions about it because it was such a long time ago, but in my opinion she is aware Sera is some kind of relative to Akai.
Also, this is the first time Sera and Okiya have been together since the Bell Tree Express (yes, it's been that long, lol). But more importantly, the first time since Mary was introduced to the series. As Okiya may not be aware of Mary's whereabouts and condition or even existence, let alone her involvement in the story, this could (!) become very interesting. I'm hoping for some kind of slip on Sera's side or maybe even Conan mentions Mary in some way. And let's not forget Haibara is there, too. I know this is Gosho we're talking about, but this case could be very plot moving, indeed.
edit: Now that I think about it, it's pretty clear Akai knows about Mary's condition - he was able to see through Haibara's and Conan's after a relatively short amount of time. I guess that's only possible if you have someone with a similar condition in your family. But nevertheless, I get the feeling that by the case's end we will have some progress in the plot. Not by much, mind you - this is still Gosho - but I'll take anything over more meaningless detective boys stuff.
