Harry just held her tight, alternately looking between Teddy and Draco, and Hermione's bushy hair. He wasn't really sure what he should do in a situation such as this. If he had known that Hermione was coming over, he would have warned Draco that she knew about them.
He didn't tell her, of course, she just guessed. Harry didn't care though, that she knew. It kind of made him feel better, knowing that someone knew; someone he could giggle about Draco with, once she got over the shock of Harry dating Draco AND liking guys as well.
"You and Ron?" Harry asked. He was a little confused. He knew Ron was avoiding Hermione, and possibly himself, he didn't really know, but he thought that at least Ron and she would still be friends.
Harry directed Hermione to a couch, and sat her down upon it. He sat next to her, one arm around her shoulder. "Hermione, do you care that Draco's here?" He looked up at Draco, "Draco, Hermione knows... she kind of guessed about us, when I told her that I had a plan in case I got sick... that we have a plan."
