Hermione stepped through the arch and into Diagon Alley, with her son lewis held carefully in her arms. She paused wondering where he would be, and then spotted him over by flourish and blotts. The only problem was Ron and Harry had gotten to him first. She darted between shoppers until she finally reached him. By this time he was on the floor, his breathing irregular and his pulse going 100 miles an hour. Carefully she bent down and gently helped him sit, he managed to bring his head level with hers and kiss her gingerly on the lips and taking their son in his arms.
Harry, meanwhile stood and watched the scene in front of him. Ron's face looked exactly how he felt, utterly bewildered. He did however notice only now that the child between the couple didn't look much like Ron at all. This man was the father of Hermione's son.
