How does that prove Buggy will be in Elbaf? Because Giants were mentioned?
Does that mean SH's next destination will be the Red Line because King being a Lunarian was mentioned?
It's just a theory. SH's obviously aren't going to the redline next. There is more evidence for the next destination being Elbaf.
Shanks Viking/Elbaf ties
Usopp wanting to go to Elbaf
Usopp brings up Elbaf in Water 7 an arc that Pluton was mentioned.
Usopp in Dressrosa worshipped by Hajrudin
Elbaf mentioned again in whole cake
Giants worship the sun god, the sun god was just revealed to be Luffy in Wano
It's the only place that would make sense to go to next. It wouldn't make sense if strawhats go to the redline then circle back to Elbaf then circle back to the redline...
