Harald flashback spanning a few chapters minimum
More than likely Harald meeting his first lover (Hajrudin's mother), maybe meeting Loki's mother as well, meeting Shanks, making a deal with Imu, etc
Then we'll cut into Loki's side when he sees Harald getting stabbed, him getting framed, all that jazz
Might not see the Strawhats for a few months at least
Lots of promising lore drops on the horizon though
