Just remembered, but it was implied by Da Vinci at the end that while most servant went back to the throne, (but can still be summoned again since we got their graph data) some servants who didn't want to part with us stayed behind (I assume it's the servants with high level bonds).
Since humanity was restored, does this mean there's two Waver's existing at present or did heroic spirit Zhuge Liang's (Waver) fade to leave us with the good ole vanilla El-Melloi III?
Don’t know about Waver but the other Psudo Servant we spend time with, Ishtar, clearly states that her and Rin have merged in to one personality wise. I get the impression that our Ishtar is a separate entity from the full Goddess Ishtar and Rin. So based on that I’d imagine that Waver / Zhuge is also a unique being regarding the Throne of Hero’s. Kind of how OG Archer and his past self are able to independently exist, regardless of timeline.
I can only imagine Waver meeting Zhuge Liang (Waver) and going "Oh, this might be a pain" with how the association is going to swamp him with all the How, what, when, where of it all...
The Waver we summon isn’t actually part of our dimension. Remember in the Fate/Zero event where he talked about his dimension having 5 Holy Grail Wars happening (where Fate/Zero and Fate/Stay Night happened) and the FGO dimension only having one Holy Grail War happened (where the creator of Chaldea, Olga’s dad participated and won). So if Zhuge did decide to go back to the throne, Im pretty sure the waver he’s connected to would be somehow returned to his dimension.
Re-watched the scene in Fate/Zero event your right. But wow it may be it's been some time but, where was it discussed in the event that mentioned FGO dimension only ever had one Grail War?
