You all never cease to amaze me. Silver cannot be a future Gray or Gray's brother. Silver came from the Books of Zeref, meaning he was created years and years ago by Zeref himself, way before Gray himself was ever born. If he smells like Gray, it means he's most likely his true father and abandoned him.
