Well, if you look at Silver's role in the arc, it is very similar to Itachi's when he worked for Akatsuki, Itachi physically and psychologically traumatized Sasuke just like Silver to Gray. There is a Necromancer, he's dead, they both have touching moment then bam Hero gets new purpose.

I wasn't really sure how or when even Deliora would be able to possess Silver at all since we have known it, Deliora is a mindless creature bent on destruction with no sentience. And when did Deliora even possess Silver when he was trapped in ice and even when he was freed?

@Carrot, I don't know about Erza vs Kyouka being the worst, I thought, Erza vs Aria, Ikaruga, Evergreen, Kagura and Jerome were the worst since they all ended on one-shots. I think her greatest challenge was Edo-Erza and they both went down and ended as a draw despite Edo-Erza's claim. I mean who can best Erza than Erza!?! XD
