Exactly....JK is known for red herrings, deception, and last minute reveals. You can't take anything at face value, but you always have to pay attention to things that happened before. Explanations are planted inconspicuously, but in plain sight. Like the locket that no one could open in Grimmauld place. I love how complex her stories are....the layers that you have to peel through to find the answers. She's really brilliant at that, and I love that she parallels it all to real world events/feelings, etc. I can't wait to watch it again!!!
