the issues or contradictions in this case would come from judai/jaden being there
as explained
here in yubel's perspective "everything" would end so there's no possible way for her to teleport or bfr herself and jaden out of the explosion since again everything would get nuked
and this brings up the other issue of jaden surviving jaden is just a normal human with no regenerative properties you can argue that yubel would save him since she has mid godly regen but as explained
here yubel would only be a
part not his entire soul nor is he part of her soul and she doesn't have any resurrection powers to bring judai back
there's also other point
@Ogbunabali made and that is "there's too many what if" but he didn't elaborate on how many what ifs are there and again yubel stating that the
explosion would end all of existence heavily narrows that down
so i'm left asking questions since no one seems to care about the plot or does it seem like anyone is trying to fix or try to answer these issues
