I hope Silver is Gray's dad who is merely reanimated by Keith and forced to follow Tartaros plans.

That would make a lot more sense than him being an Etherias who decided to fuck someone he considers to be less than an insect. Also, this way his Devil Slayer powers would make sense, since he is a reanimated corpse rather than an actual Demon.

Sting really has become Natsu 2.0 and I really like the fact that Marde was unfazed by their attempts to hit him.
