What's the point with that quite lackluster story in Endwalker?

[Aneshda]

We never made a promise to Venat. She made a promise to our WoL, that's all. There is not a single Cutscene where the WoL made a promise. The same happens with Graha he says always we made a promise / he made a promise to us to visit Ishgard together.
I can't find any Cutscene where our WoL made any promise to him or where he made a promise to us. It is kinda irritating. It is like we read a Book and Page 151 is missing.

With Graha, just before he "dies" as the Exarch, he begs the WOL to take his younger self with them on adventures, because he wants to be part of their story. I don't remember exactly how the PC reacts, but it's implied from the scene and the WOL rushing off to give the Exarch's memories to Graha later that the WOL "agreed" to do so.

Whatever we said in the "past", where he had been the Exarch, that stays in the past, cause I hate Fanboy Graha so much. I wish we could just refuse to do any Adventure with some of the Scions we dislike.

Right she’s referring to her promise to us, as she mentions in the quote you posted.
