Karin saw more than just blood leave her as Fitha was pierced by Fjore's claws. She kept in Fitha's scream by kissing Fitha some more. When she came up for air, she started to nibble lightly on Fitha's earlobe. One of her hands started to travel her body, trying to stop some of the blood. She didn't want her partner fainting on her during the time she had to act.
Deeper Love, right?
