Half-expecting Demyx to show up at the very end of Missing Link as a Drifter. Like, there's a time skip to when Xemnas was looking for new members and he just finds a soggy Demyx laying on the beach somewhere. tbh, that does strike me as the first place he would look for ancient wielders. It seems like something the Player would've told Xehanort about.
As we know, their numbers represent the order in which they were recruited. So, Demyx, number IX, was the first new member after the Radiant Garden lab crew + Lea and Isa. He was picked first. The first ancient wielder they found. It's sussy.
Thanks to the end of KHUX, we know that Larxene and Marluxia's powers as Nobodies were determined by their environment. (Larxene woke up in a thunder storm. Marluxia woke up in a bed of flowers.) So, how would Demyx get water powers? Probably from waking up near water, right?
This is what we know about Drifters so far.
The Player's amnesia was so severe, they couldn't even remember their own name. If Demyx is a Drifter, the implications make me :))
Like... He's an ancient wielder? Who showed up from "another world"? Who doesn't even remember his own name? Haha, okay. 😏
The title of "Melody of Memory" (MoM) associates memories with music. Particularly, with recalling memories. Where Drifters are concerned, you could say that water represents the loss of memories. Demyx uses music to control water. It's a halfway decent metaphor.
At first, I wasn't sure what to think of the whole Drifter thing, but now I can't wait to find out more about them bc I think this could finally be the explanation for how you go from MoM to Demyx. There would still be a lot of questions, like... Did he go through a distortion willingly, knowing what would happen to him? Was it an accident? Wuh happun?
ftr, I don't think Luxord is a Drifter. (Because I still think he's Brain until further notice.)
