This ep was mostly a padded out part of a transitional chapter or two of the manga with some flashbacks to save (waste) time. The next ep looks to be pure filler and possibly the start of a whole arc/series of completely unrelated random flashbacks /one shot episodes.
And people wonder why I say I actually preferred the filler hell.
At least you could just stop watching Naruto for 2 years and it stuffed it all at a point where nothing was going on in the story anyway.
