Shanks joining the Holy Knights utilizing his Figarland lineage is interesting.
Wonder what exactly it was that he wanted to uncover so bad for him to have undertaken such a risk

Imu's identity? or maybe simply curiosity about his lineage? Either way it's pretty interesting regardless.
Also crazy that Shanks was the catalyst for Fisher Tiger's escape. Dude has been a catalyst for a lot of significant events in the verse with the most consequential yet being the birth of Nika. Also with Loki's true nature becoming more and more apparent, given Loki's personality it could very well be that Shanks defeating Loki and keeping him chained was to prevent him from having and untimely death from reckless challenging the WG. Get the feeling that it'd be tied to Harald somehow, like a promise of sorts to protect Loki at least till Nika awakens in the current world. Really looking forward to how Oda goes about writing Shanks going forward ^^
Also back to the Shanks Holy Knight ting, according to Shamrock, Shanks decided to return back to the world of the common folk so chances are that he quit the Holy Knights. Wonder what happens to the mark when that happens. Fact that the Sea King took his arm must mean that he either wasn't bestowed with immortality or that mark was retracted after he left the Holy Knights
