I'm trying to tie this together by coming up with some crazy, clever way in which CLARA can be an acronym just like CAL was, but the closest I can get is Charlotte Lux And River, with nothing for the final A.
Charlotte Abigail Lux And River rearranged and in acronym form is exactly CLARA.
I don't really like that it needs to be rearranged, because that makes it harder to explain on-screen, but it does work. At any rate, I'm very much not banking on it being right.
