Weilan post-canon fix a different timeline for baby Shen Wei and Ye Zun by yeeting the Rebel Chief into the sun. Their alternate versions still find each other later because they always do. They live a totally different story, but it doesn't matter because the original Weilan already had theirs.

Ooh, now that sounds a) Excellent and b) Fascinating! I hope that original flavour Weilan get to watch and provide commentary on their AU selves' shenanigans, lol! :D
