After Chapter 2, whichever lead you choose to follow first - talking to Melody Flores or visiting Zinn - becomes "Chapter 3" and the other "Chapter 4". Currently, if something's from one of those chapters it's referred to on here as being from "Chapter 3/4".
My proposal is to, for the sake of clarity, use the names used in the Steam achievements instead: the Flower Arc and the Media Arc.
This'd of course require editing a fair few pages, but it's the search bad and Special:WhatLinksHere will make it an awful lot easier for us.
Should we rename Chapters 3 and 4 to the Flower Arc and the Media Arc?
