I think I need to watch the anime to understand this egghead arc. This is a clusterfuck. Are the Seraphims defeated? Did Oda just off panel'ed them? What is happening on egghead? Does anyone make any sense?
They fought for a while against the seraphim, someone found Stella and rescued him, York was captured and the Seraphim neutralized
There will definitely be a small flashback
What's interesting is Gorosei fully expecting the Seraphim to wipe out Luffy and co
Zoro found it weird how their flames are not going off, so they could truly be 24/7 flame on invincible machines
At some point Sera Jimbo didn't have flame on but maybe that's because he's still maturing compared to the others
