in dbz trunks came back to warn about the androids and heal goku. when trunks left to his time we assume everything was better and hes gone. when trunks comes back in super if hes from the future then he should know about all the events after the cell saga because young trunks is there fighting buu. how does future trunk kill bibidi stopping buu form reviving if buu is alive in the present. if future trunks is just from the future he should know things like krillin and 18, about pan, and breeus. the bigger mess up is that future trunks doesnt know about ssj3, he thought ssj2 was the highest but the mess up is that trunks knows about ssj3 and ssjb because trunks and goten fuse and power up to ssj3. wouldnt that make future trunks not apart of this timeline but make him be from a multiverse which would mean hes not part of this timelines future
