Mmm... I haven't seen this yet episode yet, but two weeks ago they annouced the filler arc at the end of the last arc's episode.
The problem with this one to me is...
that is covers some manga events like Orochimaru and Sasuke's discussions and training, and Deidara and Tobi catching the Three-tails, which this is actually, apparently, an expansion on... |
It seems a bit unnessicary to me, but I'm far more upset at how they just casually destroyed the timeline of events.
And no, you're definitely correct Goldknight, the only female I remember around Orochimaru in Shippuden is Karin, and she shouldn't be introduced for awhile.
