[spoilers for Shadowbringers and Endwalker, just in case]

For Kanae, especially after Endwalker, her feelings are a little complicated... she does not like the Emet-Selch she defeated in Shadowbringers, and while she does choose to remember the ancients per his asking, she goes about that as a historian would-- out of obligation to the ideal of keeping knowledge to pass on to the next generation. It's a bit painful for Emet to see that's all it is for her, especially given that her Azem's namesake was the goddess of memory. But Kanae isn't her, and as much as the experiences in Elpis inform her feelings towards Hades the man instead of Emet-Selch the Convocation member, she still doesn't see him as anything more than an ally for a short time, from a time long past.

W'htal does not like Emet at all, full stop. He's like a magnet to people he finds full of themselves, and if nothing else, the dramatic persona he gets in ShB gets on his nerves. The time in Elpis hardly helped matters-- it was always Azem this, Azem that, and he doesn't know or care to know who his Azem was as a person. If Kanae was aware of herself being other than Mnemosyne, then W'htal was 10 times as aware of his difference from Ammon, and was not afraid to tell anyone in the world unsundered to leave him alone about it. He remembers, but only because such a nuisance to him is hard to forget.
