The less you know about time travel, the better. The less you know about the multiverse theory, the better.
Also regardless of everything, I still can't wrap my head around the lack of Gohan in all of this. Seriously. I could say the same about Piccolo, but he has fallen behind as well since the Buu saga and is more teacher/mentor like he was to a young Gohan briefly. This is also far worse when I think about the lack of Gohan being mentioned by Goku Black...and you know what would have been great? Seeing Future Trunks react to a grown up Gohan! We saw him react to a changed Android 18....so what the hell Toriyama.It'd be hilarious if he was a Super Saiyan Blue the whole time, and achieved some other form of it
I thought of that after watching TFS do some scenes from Super and reference the new hair color.
