Hermione stopped listening as her whole body turned numb at the realization that Tom, her Tommy, had sex with a girl, and didn't tell her. There have been many times that they had sex with someone else, but they had always told each other before they had done it and who they did it with if they decided to. He didn't tell her. That's what hurt the most, and at that thought, anger flooded her body. He was the only person that could hurt her in any way possible, her only weakness, and she hated it. She hated that anyone had an advantage over her, but she would never trade him for the world, no matter how vulnerable he made her.
