I've been wondering if this line was foreshadowing Kaido drinking Absinthe during a future fight.
Kaido on Absinthe sounds fucking terrifying
I'm pretty sure Linlin is showing up on Elbaph soon, but I'm not sure about Kaido. I DO still think Kaido is Harald's Kid with the Oni Queen, so... fuck it, come on down, King of the Beasts.
I've been theory crafting about Tama feeding Kaido and Linlin while they're trapped in Seastone underneath Wano. Need to get this Moria theory together, too...
