Seriously... do you think guys that Doflamingo is gonna lose the party? Really?
We have seen all the Shichibukai wereabouts minus Edward Weevil, and all of them are alive and free!
Why would Doflamingo be the one who gets jailed? It makes no sense, he is a character that knows too much to be jailed.
Somehow he will get free, and Blackbeard making a deal for Coby makes sense too.
