Okay.here is my theory.Silver is gray's father.He was transformed from a human to a demon just like Minerva by Kyokka.When Silver was introduced for the first time he was in front of a grave.Maybe that grave was his wife's grave,thus Gray's mother.Demons consider humans to be even lower than insects.So Silver immediately could have killed natsu.Instead he put natsu in jail.He also gave Lisana something to cover and gave them a sword to free themselves.So I think Silver is not like the other demons.I think Silver may have an demon/evil part and the human/good part.There is also his "childish" attitude towards Natsu when he meet him.He laughed saying sorry for the mistake.If he were a true demon created by Zeref,he would have never laughed in front of a human,let alone smile at him.Also Gray recognised him when they started fighting.The reason why he became like that when Natsu said "Gray" was that because he is a demon and demons consider humans lower than insects. Sorry for the long explanation but that is what i think.Silver used to be human and he is gray's father.
