I never understood why Draco didn’t tell them that it was potter…
Are you kidding me? This is the moment when Draco realised that he was fighting for the wrong side, that the man who was sat in front of him was meant to save everyone from Voldemort, the one who is going to kill Voldemort. From this moment on, Draco realised that Harry was the one who was going to save him.
