Bellatrix wasn't very good at not pushing things. But considering the kindness Severus had shown her, she was willing to try. She didn't relish speaking to Draco anyway. Even if their last conversation had been less confrontational. Still, she was curious about him. It was hard not to be. He was her blood, even if he did hate her. It was a hard promise for her to make, but she'd considered her options and made a choice.
She would ask Helga if moving into the castle was an option for her. She'd not stand idly by and let people harass her. She'd do better, or give it one hell of a shot at least.
Bellatrix rose to her feet and offered her hand to Severus to rise, and to shake. It was a deal after all.
"I'll avoid him for you. I owe you a debt and I don't take that lightly."
