@Daz I hate you so much for this
At least Saul didn't die quite as...definitively...as some of the other fake-outs. Look guys, Oda needed a way to connect Ohara to Elbaf, so it had to be giants. And Saul was the only Ohara-related giant we know of.
It actually would've been MUCH cleaner and made MUCH more narrative sense if it was Dragon's Freedom Fighters that came back and retrieved the books, and nothing would have been lost from the chapter. So it's clear Oda really needed the Ohara plotline to feed the Elbaf arc. Maybe the payoff will make this whole thing more palatable for you guys.
Look, y'all hopped on this Willy Wonka boat with Oda when you let a ship repair itself and pull up on the Straw hats--across the ocean--when they needed their asses deus-exed, so don't start complaining that the colors are going too fast now
