Let's suppose that a 13th generation vampire has embraced a ghoul who has learned the first point of her master's primary discipline. This would make her a thin-blood. In this particular situation, what would happen?
Should the thin-blood gain Discipline Affinity as a bonus thin-blood merit? Must Discipline Affinity be one of her initial thin-blood merits? Does she lose the use of the discipline? Should I drop a meteor on the character that did it?
