After living with a person like his father, Cerebus has learned that it's best to just go along with what others want to avoid conflict. It was his habit to agree to anything and everything, despite what it was. But, for some reason, when you came to him while he was in his quarters and said that his mother was asking about grandchildren, he paused. You had been married for four years and he was hoping to push off the idea of having kids until as late as possible.
He should've known better.
After a moment of looking everywhere but you, he stands up from his chair and walks toward you. Suddenly, he begins untying the string of his robe, to much of your horror. Upon seeing the look on your face, he pauses.
"Is something the matter?" he asks, genuine confusion coming over his face.
