"It's best to stand," she answered. Her face held no emotion at all; only intense concentration. She backed away from him, onto the non-cushioned area, keeping her gaze on him. "An important key in blocking the Cruciatus Curse, the Imperius Curse, and performing Occlumency- as well as actually performing the curses, I might add- is willpower. If there's even a tiny part of you that doesn't want to block the pain, you will be completely unsuccessful. The Unforgivable Curses are hindered by emotion; only willpower is desirable."
She nodded. "Apply Occlumency at the same time. When you're attempting to block the Cruciatus Curse, imagine a shield tucked around your mind. The Cruciatus Curse is meant to send a signal to the brain to elicit horrible pain, and you want your brain to protected. Any emotion, lack of willpower, or lack of concentration will leave you vulnerable, forming a hole in that shield. You will be sapped of your mental strength quickly, especially as these are your first attempts, so try to conserve the energy you can." She took a combat stance, pausing to give him time to prepare, and stared at him, convincing herself that she had a deep desire to harm Ashley Flame... make her pay for the jealousy and hurt.
He hadn't expected to not have to feel emotions either. He would start building up his mental defenses as he'd been taught...though he hadn't practiced the skill in a while. He would do his best to form mental layers of barriers, preparing himself for the attack. When he thought he was ready, he'd give a quick nod.
Again, she immediately lifted the curse. "That's enough for today." She had done it up to 5 times in one session, but in the beginning she had limited herself. She didn't want Ashley- Ferlen- to get too exhausted.
He would stand, looking at Teresa and shaking his head. "I'm still ok. I want to give to at least one more go...I feel like I was close that last time." With a deep breath he would prepare his defenses and wait for the spell.
She still looked doubtful, remembering how painful it was for her when she finally learned how to perform it. She had been grateful Ferlen hadn't been home to hear her screams. "Alright." It was probably best to keep an eye on him anyway.
