LML bloodfiends barring the two of them who actually wanted to change the flow wanted nothing more than to simply stay in their castle and just gorge on blood. They didn't care for anyone or anything else, and actively disliked their Father's antics about trying to find something to do because to them the ''family'' alone was enough. Apathy is a part of their sickness as well.
