Any person who was a human or any other creature who wasn't another pureblooded vampire or a werewolf was meant to be scared of a pureblooded vampire. In the past, Eve respected Marceline like any other person from high society, as she knew where she stood compared to the other people around her. But she didn't have to hold the same respect or wariness towards the vampiress.
Marceline had humiliated her in front of every person in Meadow, causing Eve mental and physical pain. But it ended there. Knowing the vampiress didn't have fangs anymore nor her family's support in hurting Eve, Eve didn't have to bow her head to this woman. The vampiress was reduced to nothing less than a human, who drank blood from the glass.
