User blog comment:Rfx9416/Theory: Eustass D. Kidd/@comment-972068-20141114212118

"Just a theory, but i have a decent amount of tentative evidence to back it up." You kind of have to in order for it to be a theory.

Anyways, that's an interesting way to put it. Kidd is sort of connected with Luffy the same way that Law is (aside from the pirate alliance and the Marineford thing). Still, I don't quite see why Kidd would keep it a secret or anything.
