The almost heartbreaking but also moving thing is imagining Zoro and Sanji in Rayleigh and Gaban's places while interacting with Luffy.
Imagine if Luffy was dead,and Zoro and Sanji years later met a kid who was similar to him,and they had to teach him how to become a better pirate.
Thats why we can understand Scopper Gaban scolding Luffy so hard in this chapter!
For him,its not even so much about saving the world,but about giving the right tribute to Roger,his captain!
Thats why this was a great chapter
