Why are they all still on the ground ‘sleep’? Unless they didn’t get their heartless killed until later, they got their body back at different times. For Vexion, Zexion, and Lexaeus they would have been on the floor sleep for a year since this is from Axels POV. Axel, now Lea, who became human close to the end of KH2, while those 3 ‘died’ in C.O. beforeSora took his year long sleep.
Plus why does Lea have an OXIII coat on when the others don’t? They went back to the clothes they had on before they became a Nobody. So before Lea became a Nobody, he was already wearing an OXIII coat? How weird. I’d imagine the others would have one on, not Lea since him and Isa went there for some objective. So maybe their objective involved them already having a coat before becoming a Nobody? If so, how did he get the coat/from who?
Plus, what was Axel doing between Saix, Xigbar, and Xemnas becoming whole and the perfect timing of showing up to save Sora in KH3D? Maybe that will be explained in KH3.
I don’t know for Ienzo, because the explanation I’ve heard most and liked best is that Lea has on the coat because his old clothes wouldn’t fit him anymore, as he’s aged.
Plus, Lea still needs protection from the darkness, which the coats provide.
