And bullshit Silver wasn't inconsistency. That is inconsistency at its finest. Silver had never, ever met Natsu before, and the first time he got wind of Fairy Tail (and Gray by extension) was during Day 5 of the Grand Magic Games, which Natsu was not part of. So that's Silver knowing Natsu being an inconsistency, because the only one that could know Natsu was Deliora. And then there's Silver having a 'human form,' which would have made him unique if he was a demon. However, it became clear that all the other demons knew that Silver was indeed just that: Silver. Therefore, that became inconsistent. Hiro changed his mind a few times before settling on Silver, and that included during the writing process. It was fucking terrible.
