I said the same thing on discord.
Spoiler: showThat hopefully they make this quest line mandatory for Endwalker because I’d love to see more of Gaius continuing his redemption arc as part of the MSQ.Spoiler: showWould they have to make it mandatory? My memory is a bit fuzzy but wasn't his introduction and storyline in Stormblood loose enough where they could fit him back into the MSQ without having to do anything?
