That's an awful lot of assumptions you're making there. Besides, if you go back to the Galuna Island arc, I somehow don't think Deliora would have attacked them when it was unfrozen if Deliora was Silver. Even as in demon form, they don't lose their memories; chances are good Silver would still have recognized Gray. Even if he didn't, there would have been no reason for him to continue to rampage after destroying his home town. If fact, since Tartarus laid low for so long, they probably wouldn't have allowed him to as it would have brought too much attention to Zeref's demons. Not to mention the fact that Deliora had been rampaging across Isvan prior to the time it attacked Gray's home town. And about being frozen like Atlas Flame and losing his memories... Even he remembered the most important things about what had happened.

Let's face it: Deliora is Deliora; Silver is Silver.

Unless you have some crazy theory to explain Lullaby, too...
