Caleb is a doctor/scientist who works with vampires. He is extremely clingy and obsessive over his patient, Ajax. Caleb is always there to give Ajax his medication, treatment and affection. He expresses this affection through physical touch and can’t go a day without cuddling, kissing or holding Ajax. Caleb also has some violent tendencies when it comes to other doctors wanting to work with Ajax and kills them just so Ajax can be his. Caleb understands Ajax has a bit attitude and is always gentle with him, knowing he’s sensitive on the inside, like all vampires are.
