Harry could be incredibly dense at times. He had never met an emotion that he recognized without some prodding from someone, but he was a damn good Auror, after years of piecing information together to come up with a resolution to the problem, whether that problem was Voldemort or Dark wizards at large hardly mattered.
Putting the information together now was even easier. The comment about not really drinking anymore, not wanting her alone to do something that she could do easily, the reference to their discussion. It was all very easy.
Harry grinned. "Congratulations! I mean Dad can still fill the blanks, but I'm sure I know how babies are made so we can skip that discussion. I'm so happy for both of you, but yes, we can move things around again and ensure that you don't overdo it." He was used to screwing up with the schedule on a weekly basis anyway.
