In her hand was a blade from the kitchen, She held it up to her throat, fingers trembling. Her knuckles were white. "I said I wouldn't let you."
"Rose… stop. I can't escape from this. They'll find me."
"Then we'll do what we've always done! We'll run!"
"You can't run forever. I've tried."
She pressed the blade to her throat, the cool kiss of it drawing blood that ran in crimson lines down her neck. She grit her teeth and growled, "Don't doubt me, Doctor."
He sighed, "Put down the knife. I have to go back. If you do this, it'll be worth nothing."
"Without you, I am worth nothing. Don't ask me to live my life without you, Doctor. It can't be done."
He walked slowly, cautiously to her, reached his hand towards the knife. She jerked backwards, another wave of crimson cascading down her neck, dripping into her heaving bosom. She trembled still, despite the resolution in her eyes. He let his hand fall back to his side. "Alright. I give up." He treaded sullenly to the console, his features drawn. He guided them into the vortex, then to his destination. "Let me make sure we're in the right place." He opened the doors and stepped out. The doors locked behind him. Rose dropped the knife, and it landed with a clang on the metal floor.
"Oh don't you dare!" She snarled, and ran to the console. Dematerialization sequence began. "Not again." She found the pane which she had previously pried off in order to return to the Doctor. To her immense surprise, the pane fell off at her fingertips. Once again, she was encased in the beautiful golden light that was the heart of the TARDIS. She let it fill her. She was Bad Wolf once again.
