Disclaimer: I own the character Katrina and no one else the is for J.K. Rowling
While in the hospital wing Harry was thinking about Draco and how he woke him from his nightmare. Harry was so baffled that he didn't notice Draco walk in the room.
Draco entered the room and saw that his dear Harry was awake but not to himself quite yet. He wanted to talk to Harry any way so he made Harry know he was there. He had something important to tell him. When Harry got out of his stupor he was really excited to see Draco again. He mad a move to get up but Draco stopped him in his tracks. So instead of fighting with him he sat back down and asked him if he came to save him from the awfully quite hole once at last.
To no avail he said no not yet at least give it another week. When Harry heard this he was kind of sad but happy that he at least got to talk to Draco. However when Draco said he had something important to say he got scared for some reason. That changed though when Draco said that Harry no longer had to go to his house on Privet Drive anymore. Then he got curious as to why that was. Draco then told him that his Aunt Katrina (Snape's daughter) had put Harry under her own care as well as Draco's care. Harry was so excited that he jumped off the bed and into Draco's arms so fast Draco lost his balance and fell down with Harry in his arms and on top of him. He was blushing horribly with his hopefully future boyfriend on top of him unexpectedly. His embarrassment just got worse when Katrina walked in on the little situation.
Also the nurse came to check on Harry and saw it as well. He quickly got up and got Harry back on the bed and got him to stay again. He then heard his aunt laughing at him. When he glared back at her she stopped and went back to standing there. For a while it was quiet then Katrina broke the silence saying that Draco need to come finish some paperwork so he could be Harry's legal guardian.
Draco never did understand his Sister/aunt Katrina. The reason for this was that she was his biological sister, was Snape's adopted daughter, and was dating (and soon to be engaged) to Oliver Wood. Also when she went to school at Hogwarts she could not be sorted into one house. With that the sorting hat decided to let her choose witch house she wanted to be in. Since then she was in the Gryffindor house. Another thing that bothered him was that she finished school in two years instead of seven. She was also a prefect when she started her first year. Katrina also became a teacher at Hogwarts, she was also a player in the Gryffindor quidditch team. That was even more bothersome because, she was a teacher.
When Draco came back to his senses he told Harry good night and left after Katrina. Sadly he did not notice the very sad, jealous, and now lonely Potter.
