Severus was completely in his head. He had missed Bronte playing with her food and Louisa was obviously, to someone bothering to observe, frustrated to the point of allowing herself to take it out on the baby. Usually, he would have stepped in and taken care of the situation before it got this far, but he wasn't paying attention.
"At this point, I think we need to keep it as secret as possible," Severus moved his chair slightly closer to where Bronte was and handed her her fork. "I don't think Rabastan will say anything to anyone until we decide we need to." But there will quickly come a point where Rabastan would make sure his family was in the know. "And I will just have to... find out more." How he was going to find out more, he had no idea.
