Some new titles above. Reading them they may seem like the start of Shippuu-den, but I’m not sure they make sense in context. As there’s no Kakashi Gaiden, it’s missing the introductory welcome back episode and it would cram like 6 chapters into two episodes which the series has never done before. So I would guess it’s some type of Suna filler to get them back in your mind before part two finally starts.
