I think Zenos is fine with waiting as long as he needs to if it's giving him and us more time to prepare and ensure the eventual reunion will be as satisfying as possible.
I am a touch curious as to where exactly he intends to find a new weapon since he evidently wasn't satisfied with the one he got from Yotsuyu and legendary swords with mystical powers don't exactly grow on trees.
On the subject of Fandaniel, I think I'm most curious about when exactly he became the way he is.
Namely, are the Telophoroi a group who existed back in time of the Ancients, or are they a more recent development, perhaps formed by sundered Ascians who have grown sick of Convocation's obsession with chasing their perfect world and intended to rebel the instant a suitable opportunity presented itself?
The mention of him finally being free from his memories does possibly imply that what he wants is not what his unsundered self would've wanted, but only time will tell.
