Regarding Nautilus
Maybe it really doesn't matter with the retcon, and the game seeming farther and farther from the lore, but I've always been curious about what the ooze was that converted Nautilus. With the glow that Naut has, along with the transformative effect and feeling of veiled horror that Naut's lore implies, it seems kind of like a Shadow Isles thing, but if that's the case, why did he defend Bilgewater? Speculation Ahoy!
Off Topic, with Nautilus seemingly very focused on vengeance and revenge, maybe some special interactions with Khalista? Rito pls?
