Ren continued to drown her mind in pain, and began to place images of death, and screaming for added benefit. He squeezed at her hair as she clawed at him, and his grip on her tightened. He forced her to remain standing, watching her claw and scrape and fight, and only caused him to intensify his mental torment of her brain.
He stared down at her, tilting his head slightly, as if curious, her screams enticing him, he loved it the way she cried in pain. He just stared back down at her, saying nothing, asking no questions, making no point, just letting her wallow in the pain of the moment. He had felt her resistance, but it was futile, he had all day, and he'd not let up until she realized the pain was never going to end.
The pain began to intensify, pushing to a level of blood red, his eyes locked to her behind the cold, emotionless mask, waiting to see if she'd beg for reprieve.
