Severus snorted when he read Draco's note. He'd suspected Draco had something up his sleeve and he suspected it had something to do with Umbridge. The idiotic woman had always had a limited lifespan in the role she'd usurped. There were too many people in the community who had negative opinions of her to accept her in the role. If she had one iota of common sense, she'd know that and have done something about it before assuming she could just waltz in and not face opposition.
Well, he wasn't going to miss this for the world. Draco was always entertaining to watch when he was in full plotting mode. He waved the house elf over and handed the creature his reply.
I'll be there. Are you going to tell me what you have up your sleeve or are you developing a Gryffindorish need for the big reveal?
