He was on the shores of Wano and the RHP even mentioned to go to see Luffy, it was Yasopp who said it specifically IIRC but Shanks refused and said iTs NoT tIMe YeT because I'm a bitch and I have colder feet than Kuzan /s.
Seriously though, Shanks was right there, bullied Green Bull the Bully as he deserved after godly flexing of Haki and some amazing panels BUT then decided to fuck off for no reason, after claiming he just xame to Wano to chase after Blackbeard who he believed was gunning for Wano.
He then mentions he needs to go after Bartolomeo for attacking one of his territories but as we know now, he went to Elbaf instead for some fucking unknown reason and had to bully the dumbest Supernova, Eustass Kiddiot. I love Eustass Kidd a lot BUT he was fucking dumb in that moment, sigh. What did he think he would accomplish? Why not target Shanks directly instead too? Such stupid writing but whatever...
I guess Mihawks habit of postponing rubbed off onto Shanks then anyway lol.
I do think Oda will kill off Shanks and thats why hes trying to make him look as great as possible and giving him "his own movie" and such. The fact that Oda hasn't bothered to give him an arc yet and had him acting weird/erratic and refusing to meet Luffy EVEN AFTER Luffy gets officiall made a YONKO now and DEFEATED MOTHERFUCKING KAIDO, Shanks still doesnt want to see him? FUCK OUTTA HERE ODA!
Sorry but that legitimately pisses me off so much genuinely lol. I can see Oda doing the Shanks death for the easy drama/tragedy and to gain massive clout for One Piece, controversy for views/gains. One Piece's "Jiraiya vs Pain" moment.
