Thank you.

Snape has resolved them to his own satisfaction, if that makes sense. He'll no longer obsess over Lily as much as he did.

And Lucius is also recovering. He refuses to regret his actions over the past few years because he can't change them; on the other hand, he also refuses to waste any more time chasing after Narcissa.

Hopefully, Harry and Draco will indeed last, as long as they keep an eye on what their obsessions are doing to them at the moment.
