Watching the Bahamut summon gave me an idea...

The lore reason for the Trance was that we weren't strong enough to summon Egis of stronger primals.

Not quite, it didn't have much to do with not being strong enough, because if that were the case, drawing power from Bahamut (one of the strongest primals) and using his ahk morn and teraflare should have been impossible. In my mind that takes more effort than a pickachu sized egi. To reinforce this, the ascian in the quest is even in awe that the summoner's mortal body was not destroyed by the trance alone like it was a huge feat. The lore reason was that each summon was consuming the SMNs own aether, and we already had 3. It wasn't that we weren't strong enough for ramuh. That's the very reason they came up with drawing power directly into the summoner to bypass the limitation of having egis hog up our individual aether. It'll be kinda silly if they go back on that. Unless we kill another summoner and our trainer is like ''you have absorbed all his aetherz now you can summon unlimited egis!'' It would be less silly had they not already established the fact that summoners of old used the same techniques to bypass the egi limitation.

I'm curious how the actual SMN quest will turn out. My theory is that the Bahamut summon is actually just a visual representation of the SMN being uber deep into the trance that all the bahamut aether around just manifest itself in his form. I would not be surprised if that were the case.

I just hope for more trances, hopefully an alexander attack next
