I think that he could be Gray in the future or Gray's father. Gray was always the "Susuke" while Natsu was the "Naruto" in Fairy Tail. It could be very possible that Gray became rogue in the near future and learned Demon Slaying magic and changed his name to Silver. Still, I think the father thing is more likely but then Gray becoming the Sasuke of Fairy Tail would make one hell of an epic story. Oh and btw... I think there is a chance that Gildarts might be connected to E.N.D.
