Oak might be a backup rapper, which I think would make more sense than being a cameo, as they seem to be shooting without an Ash.

Of course, it could be Oak vs Darwin, but that doesn't match up with the possible hint of Jessie from Team Rocket, as Oak isn't really associated with them in the anime. If they cameod, it would be with Ash present.
