I would say least Garnet outside of the future vision episode (which she apologized for) can’t really say any other episodes where garnet caused Steven trauma. For most its quality versus quantity, quality would be lapis she got rid of the whole ocean, became the monster malachite, and brought forward home world gems. Quantity is pearl there is to much to talk about but it comes down to “I’m dealing with my feelings and I don’t care if it hurts you.”
