is he really here in the past? what hapened to fighting in the future? can he rally just cut through time like that or is he just looking?
honestly, i hope it's the latter. back int eh day, Dragon Ball knew how to ramp up the suspense with a getting prepped arc. i want them to still have to go to the future. pack snacks and gear, pile into the ship and have a heartfelt farewell before embarking on a daring journey.
if not, then the storytelling's just gotten lazy
