Yeah it's possible, but I remember someone saying because she has green hair and then the emerald dragon that the FT dragon slayers ran into. I guess they linked it with Natsus pink/fire, Gajeel black/iron, Wendy blue/air, Laxus yellow/lightning and so on and so forth. Even though all the DS hair does match up with their corresponding elements (even cobras and the twin DS) it could just as well be mere coincidence lol. Anyway it's not enough evidence to assume that is she actually is a DS but its an interesting subject.
