Mr. Ollivander: Curious... very curious...
Harry: Sorry, but what's curious?
Mr. Ollivander: I remember every wand I've ever sold, Mr. Potter. It so happens that the phoenix whose tailfeather resides in your wand gave another feather... just one other. It is curious that you should be destined for this wand when its brother gave you that scar.
Harry: And who owned that wand?
Mr. Ollivander: We do not speak his name! The wand chooses the wizard, Mr. Potter. It's not always clear why. But I think it is clear that we can expect great things from you. After all, He-Who-Must-Not-Be-Named did great things. Terrible! Yes. But great.
