Hmm... You have discussed when Okiya will be revealed as Akai. I'm telling my own opinion now.
I think that Okiya will become an ally with Conan&co(including Ai, Sera and FBI). Jodie probably will be a bit suspicious about him(if she somehow finds some similarities between him and Akai) but others will be fine with him.
And after "the final battle" between Conan's gang and BO Okiya, Conan and Kir will tell everyone the truth(BO will never know it and curse how did they get defeated by the FBI that hadn't the Silver Bullet).
Or something like that...
