Draco’s seriously made me so happy. I can totally see his character developing into some kind of magical doctor. You know, instead of hurting people like he did his entire career at Hogwarts, now he’s helping save them. Whoever did this, well done. Well done.
My headcanon is that Draco went on to specialize in the the treatment of those with permanent or semi-permanent damage due to curses, as a way to atone for what the Death Eaters did.
He’s actually made some amazing breakthroughs, helping and saving hundreds of witches and wizards. One day he hopes to reverse the damage done to Frank and Alice Longbottom. Since it was his aunt who did this to them, and he treated Neville so poorly, he feels it’s only right.
