I thank him and leave the classroom and as I expected Draco is waiting for me. We walk towards the Great Hall for lunch, the perfect moment for me to train more. Not only do I need to be able to find people but also not make it very noticable. When I am capable of following someone's magical wave I can even use it against them, I can track them and block their spells early due to the change I would be able to feel. Hopefully one day I can syphon energy and power from it, it is rare that someone is able to do that, but I need to try.
