Hmm I was just thinking about this, my thoughts are that Gray's father survived Deliora's attack but was restored as a demon since he was likely critically injured. Then made some sort of deal with the Tartarus guild master in exchange for new life, that involved eliminating those who could destroy Deliora meaning Gray. Because if Gray (and Lyon) is out of the picture then they could revive Deliora with no one to stop him. Since demons are immortal perhaps Silver was looking for a way to die and Gray is his answer. So he tried to convince Gray that he was actually Deliora so that Gray would not hold back and try to kill him.
