Blaine noticed the way Nott didn't mention whether or not Tracey was there, but it didn't matter. He knew she was. Probably upstairs waiting for Nott, ready to flash those big wide eyes at him and then spread her legs like a common tramp.
Drawing himself up to his full height, Blaine stared menacingly at Theodore. "You're sticking your nose where it doesn't belong, Nott. What I do with my woman is my business, and none of yours. Back off, or I'll make you." His eyes flicked towards the stairs as he added a bit louder, "That goes for you, too, Tracey. Stay away from Amelia or I'll come find you at one of your little jobs and remind you exactly who is in charge."
