Well, I did only mention that as a theory; besides there's still plenty of Hime's backstory that hasn't really been uncovered yet, so it's alright to speculate if just a little.

On the other hand, I guess I might have been too hasty with my earlier theory. A more likely and plausible interpretation of Yuzu's words would be like this: when she spoke of both of them having the same rhythm, what it could actually mean that both Yume and Hime might actually possess that same rainbow-like aura that can mysteriously enchance an idol's overall performance and abilities.

Remember way back in episode 1, when Yume's eyes were glazed over with that rainbow aura? Her performance instantly improved by leaps and bounds, but after that she fainted and couldn't remember anything about her stage debut afterwards. Here's what I think; it's possible that Hime might actually possess that very same ability.

Basically speaking, I'm guessing that's the main reason for Hime (and Yuzu) to have a major interest on Yume over the other new idols. Also, it might also explain why she's in cahoots with Mr Jin Norizuki clone; both of them might know something about Yume's ( and possibly Hime's own) ability.
