Dean put his keys into the ignition. He looked in the review mirror. Isabelle came running out of the diner with a fierce look on her face. He ignited the engine and put the car into gear.

The backseat door opened and Isabelle threw herself in the car.

"What the hell?" Dean asked

"Demons? Well I'm going with you" Isabelle said.

Dean put the car in park and turned around.

"Out of the question"

"I saved your butt last time, you might need my help," she replied.

"No" Dean said.

He was not bringing her with them. He didn't know what they were going to face and he wasn't going to be responsible for her. He looked to Sam. Sam turned around toward her.

"Listen-," Sam started.

"No, I'm going if it gets out of hand, I can call in backup" Isabelle said.

Sam looked back at his brother and shrugged. Backup sounded nice for once, but Dean didn't want her coming.

"No and that's final"

"I'll just follow you anyway," she said.

"How?"

"I have my ways" she smirked.

Dean sighed and put the Impala in drive and took off. In the back, Isabelle's cell phone lit up her face.

The first 10 minutes of the drive were silent. Then Isabelle spoke up.

"Where are we going anyway?"

"Not far, we think the demons relocated to another abandoned factor" Sam said.

"Sounds like them" she said.

"No offense, but aren't you a bit young for all this?" Dean asked.

"No" She said.

Her tone made it clear she wasn't going answer anymore questions. She pulled out a pen like object and started making marks one her skin.

"What's with the henna?" Dean asked.

She ignored him. He pulled up a ways away from the factory. They got out of the car. Sam and Dean open the trunk and loaded themselves with a salt, shotgun, and holy water. This time Dean took the knife. He handed Isabelle a shotgun. She didn't take it.

"I'm covered," she said.

She took her gold bracelet off and it became a whip. Dean tried to hide his surprise, but Isabelle noticed and smirked.

"Alight, Catwoman, let's go gank some demons," he said.

The three of them headed toward the factory.
