A while before the 2chan rumours, I'd taken to calling her "A" (Ay), because I was sick of having to say "that-girl-who-looks-like-the-master-sword-or-wind-waker-queen-fairy". Hey, if the rumours are true, I got the first letter right! xDDD Kidding, but I'm just going to call her Adelle until further notice. I actually really like that name for her, and it does have some logic behind it. Apparently, "Adela" was "originally a short form of names beginning with the Germanic 'adal'' meaning "noble". Saint Adela was a 7th-century Frankish princess who founded a monastery at Pfazel in France. This name was also borne by a daughter of William the Conqueror."
So if that is her final name, it's a good choice, and if it isn't, I'll probably still end up calling her "Adelle" sometimes anyway. But think about this; what if you could name her ingame, like you could name Epona in TP....
