Imagine if the cover story was the prologue for Wano Act 4
When your entire Agenda as a One Piece fan revolves around this guy:
Telling Blackbeard about Pluton...
I thought Oda would give Teach Cerberus originally because Pluton = Pluton, the God of the Underworld, and Cerberus is the watchdog. Shamrock's fine, too, though, I've had Shanks slotted into Act 4 for years. Figarland Family Reunion. Hell, summon Garling in a circle.
Kuzan is the key here when it comes to Pluton, though.
Once Caribou tells Teach about Poseidon and Pluton, good ole (spy) Kuzan will call up the WG, and say "Uh, guys... this crazy ass Swamp Dude showed up and told Blackbeard that Pluton is in Wano, and now we're invading the country. Halp. Send Halp."
IMO Yamato's cover series will end with her discovering Pluton but us not actually seeing it fully on panel. Maybe a silhouette if we're lucky.
Cross Guild will also move on Wano, only question is if it's Yamato's Cover Series, or not. Buggy is going to use his time with the Roger Pirates and Inu/Neko and Momo to accidentally form an alliance.
