Harry! His alpha. Harry had saved him, he had turned his life upside down and saved him from a lonely future. He loved Harry, more than he had words to express. Harry wanted children, Severus had never wanted children, but he had accepted that his role was to give his alpha children. Whatever Harry claimed, Severus knew that alphas desired to have their own children. What would he do with this small person who would be completely dependent on him? Was he up to this? Could he manage? What if he did it wrong? It was not like a potion; he couldn't just discard it and start over if he made a mistake.
