Im curious if this is a break in the arc like we got with Egghead and even Wano. Lately Oda has needed to update us more frequently on outside events, to the point where we got like 6-7 chapters in Egghead that weren't directly related to it.
Maybe we'll actually see what the other players are doing before whatever happens here happens with Imu.
I have following scenarios:
One: - Imu comes here/boost Kilingham and Sommers and really wrecks anything, drops some lore drops and leaves because of a timelimit
(In this scenario the arc would last at best 10 Chapters, since Imu coming and wrecking around would take 3-5 Chapters at best).
Two: - Imu comes, Alliance fights back, Sommers and Kilingham getting 1on1 battles, the Alliance don´t get defeated
(In this scenario the arc would last over 20 chapters).
Third - Imu comes>little break to see a overview situation, third fraction joins the party
(in this situation the end of this arc could take over 30 chapters).
My guess given all the tease/hints, scenario one will most likely happening.
Imu wrecking everything and leaving...
