Considering Venat is Theia's mother, how does Theia end up handling everything with the Mothercrystal fight and the story from then on as canon dictates it?
not great, she only just (as of late shb) got atleast partial memory back of presundering, and one by one those she knew from the convocation have gone. every time she regains someone or a memory of them they are lost soon after (emet, elidibus, lahabrea). she had a gut feeling that once she remembered who hydaelyn actually was, the same would follow
after the fight itself she remains in the aitascope/aetherial sea just processing what had happened. the others head up to report the updates while wint stays behind to comfort her.
she does get increasing amounts of idk, survivors guilt, until wint chirps up with that 'hey, venat put you in that aetherial sea because she wants you to see the world! once we get this sorted we gonna take you to see all of the things, also she'd be so proud of you ynow? for all the stuff you have been able to do'
and by the time we get to the end of endwalker, after everyone has recovered from the big last fight, the gang (graha, alisaie, alphinaud, and wint) all pitch an idea to tataru:
she then goes on with the thought of "mum has gifted me the ability to see this new and sundered world, im not going to waste it /determined" so she takes every opportunity to stop and admire the scenery, try every new food or drink she comes across, and meet the locals in whichever region she finds herself in. especially now that she has finally solved the original issue (the final days) she has time for more extracurricular activities
also, sylbwyda offers her and slafzedyr to become her unofficial adopted parents, just if she wants someone to talk to, or somewhere to sleep, wants a warm meal etc, shes more than welcome to stop by for however long she wants. sure theia might be technically older than anyone else theyve ever met, but she still needs family she can turn to
