At the very least there will undoubtedly be some mention of it. If Oscar is with Qrow now, which consequently means that he's now with Ruby and the gang, then I highly doubt Ozpin's presence will remain a secret for very long (Ruby is like the most inquisitive character in the show). And once that topic gets brought up, they're gonna HAVE to explain how the hell Ozpin is living inside Oscar's head.

Or they might just blueball us and have them ABOUT to explain it, when suddenly Haven gets attacked and it gets put on the backburner.
