Wait, how did Feferi get more eldritch?

I mean, her absolute disregard for Jade’s distress after experiencing horrifying Eldritch Visions, her nonchalant “Because, silly, I am DEAD!” moment, after creating the Bubbles and spending enough time in them she kind of got. Visibly desensitized to the weirdness. Where Aradia seems to stay behind to make the passing easier for newcomers like a sort of Guide of the Afterlife, Feferi just sort of throws Jade right into the Eldritch Pool with a giggle.
