that is a .... good question and i just asked them, but i don't imagine noah and jane would have lasted very long in the big picture. all the same, she would have been all about befriending elisabeth on their own, and in the context of double dates! maybe things were mutually a little wary at first, but they were eventually like this is stupid? i like you fine? and anyway, jane and noah technically do still antagonize each other but it's more out of habit/refusal to apologize at this point than strong ill will. so elisabeth has her blessing to call her a dumbass.
