Eh, I remember most of them are ASS. Lol. Ass. Anyway, yeah, this studio hates SS now. A lot. I have no idea why. Even when they do treat it, they do it for a moral like "no good" or "see, you once were bad" or whatever. Part 1 filler is your chance to make it seem like SS but even so, it's the usual I don't like you, but he likes you but you seem to detest him and so on. I am still wondering where they get the idea of "used to". Unless we truly missed it.
I'm still suspicious of 306 (I think that's the episode)
This was only a few episodes after 540, Kishi must have told Peirrot something for them to make that bold of a leap after what happened (also maybe I'm just getting my hopes up but if Naruto wasn't the someone else than 631 would be the far more appropriate time to bring up the someone else rather than her simply turning down some random dude like she did with Lee a long time ago)
