Everything’s been spelt out. Joseph and Jotaro tended to Abdul’s wounds and made plans to meet up after he healed and bought a freaking submarine. Kakyoin was let in on this at some point, it’s unclear when because when Polnreff was stating he would come back to bury Abdul properly, Kakyoin did seem to be mourning as well. Eventually, when he did learn, he suggested not telling Polnareff, they needed secrecy in Abdul’s recovery and further plans building off of that. Truthfully, it did appear to work, Cameo thought Abdul was dead.
So ultimately, Polnareff is the main character and we only knew what he knew. It feels pretty cruel though, especially with Joseph acting like Abdul wasn’t on the island, and referring to him as if he was dead as they saw him in disguise. Wasn’t that a little far!? Ultimately Abdul was the one to save Polnareff on this island anyways but it would serve to stop anyone from eavesdropping, as it was to crush their foe when Abdul revealed himself. That said, if Judgement's user is alive, he could still report to Dio. Oh well, seeing everyone act like they saw an old friend rather than a ghost made for a funny scene.
I seem to recall the gang pretending that Kuwabara died when he hadn’t in Yuyu Hakusho as well.
Anyways, this super secret entry into Egypt wasn’t so secret after all because a creepy little stand is aboard, tearing through Joseph’s arm, yet again, and proving itself to be a true threat. Something which can morph into anything and trick the eyes while planning an attack, all in a small space, with no means of escape. This sounds like it’ll be a blast. I wonder where the user is.
The map of the journey so far was a great touch, we’ve about made it and it’s been a long ride. It does create the feeling of a road trip, able to look back at every stop.
P.S. More than for anyone, the art style seems to have changed when it comes to Abdul. His eyes look massive compared to how they were earlier.
