even if the Holy See pronounced him "dead", obviously Alberic isn't convinced of that at the end of the Dragoon quest. He even flatly states "I can only hope that Estinien is still out there", lo and behold he is. Final Fantasy has always been a case of habeas corpus when it comes to not only your comrades but your enemies. Unless there's a body clearly splayed out on the dirt for you to prod at then never believe that someone is dead.
As for how Estinien simply "walked out" with the Eye? Well if he's the Azure Dragoon then we don't know how far that authority carries or what the limits to it, if any, actually are. He could have fought his way out, simply picked it up and said "this is mine, now" and because lolazuredarguun status the guards had no reason to stop him, or most likely since he knows how it was stored and who or what was guarding it, he was simply able to steal it with minimal effort.
As for as him showing up POST lvl 50 Dragoon quest, if that is in fact how the timeline is going to place it, then I would simply say that Aymeric is the type who is obviously willing to bend the rules to get what he wants. Overlooking something like "misplacing the Eye" for a few days wouldn't be beneath him. Especially if he can bring the power of an Azure Dragoon to bear against an overwhelming Dravanian Horde.
