I believe this future side arc might continue for a few more chapters to bring everything full circle, in an inside-out manner. I have little hope with time jump-based story arcs (Hitman Reborn, Dragonball Z, RaXephon), so I hope that this isn't touched on too often after this. Let us readers paint the picture ourselves in this instance. In all, a slightly confusing chapter and one of the weakest since the underwelming mummy army battle.
