OH i very much like the idea, i think if neph actually has ways to manage anxiety and memory problems then it would help stop levi from being left out in the cold when they started to manifest. i feel like even with their doctors they were probably kind of reluctant to talk about it when they were just starting to get used to their new life outside of their ivory tower. having someone they could've started getting help from who isn't in the medical field is a very good lifeline for them to have!

as for powers... yes, yes, absolutely. i kind of have it figured out that levi manages to ground themself every morning after they wake up, but there's definitely still some room for trial and error in how that actually works. i'm very, very into this, let's have them be friends and pseudo-siblings!!
