Narcissa is going to have a little talk with Lucius.

There are still some problems left. (In fact, I think Lucius is one of the lesser problems, at least since Chapter 23, when Draco was able to successfully win his freedom). Everything you mentioned will come up again and need to be addressed. Hermione and Ron are going to be an especially sticky problem, since Harry will need to tell them the truth, admit he lied, and still make them understand that he isn't giving up Metamorphosis or Draco without losing their friendship.

And there are some problems building between Harry and Draco, too.
