If Morgan considered her night with Arthur, she only did so in thinking it weakness. The sheer need and desire she held was nothing but a flaw in her armor, and something she knew could be used against her. So she said nothing, nor whispered of the night they'd shared. She knew Arthur. He was probably feeling enough guilt for the both of them.
She shoved the memories from her head. It would not occur again. She had more important things to consider. She'd been idle for long enough. It was time to act. She'd called in her son and sat at her desk, waiting for him. Mordred had come from her body, even if he'd been raised by another. She considered it fair trade for him to do as she pleased. She'd regretted his death, but if it was needed she'd do it again.
