i'm not convinced margo is going to be her name. partly because i don't like the concept of peripheral media (like comics) in general, but also. if you could see the future, and knew someone was going to realise they're trans and change their name from x to y, would you really want to preemptively call them y? especially when there's a gender-affirmative name that's barely distinguishable (in speech) from their birth name, that you can use as a placeholder until they figure it out for themselves
I mean keep in mind Glossaryk operates on Blue and Orange morality. It may not make sense for us to do it, but it does for him.
