So eventually both Adams leave the forest and live in the city. Adam R’s family members have become extremely wealthy, and want to use him to develop the now viable land out in the desert. So they take him in and teach him the ways of the modern aristocracy– most of which just baffles and annoys him. Leeman tries his best to make sure he doesn’t act too crazy, with about a 60% success rate.
It’s only much later, after Adam R murders a bunch of anti-vampire activists for hurting Leeman that he realizes what social graces are all about. He realizes how much he missed killing people, and becomes an assassin.
It’s then up to Leeman to find a way to stop Adam from becoming a monster.
