The Doctor explained who he was and what he did. Sam and Dean just stared at him.
"You're lying," Dean hissed. "You're some sort of monster."
The Doctor's face darkened. "Some think that."
I stood up and looked at Dean directly. "Dean freaking Winchester, just stop being a stubborn jerk and actually listen to someone else besides your thick skull!"
Dean stared at me and then stood up and walked away. Sam just stared at me. I sat back down next to the Doctor. Sam cleared his throat.
"I'm going to go talk to Dean."
I nodded. "Okay."
Sam walked away after Dean. I looked to the Doctor. "Can you believe they're my cousins?"
The Doctor smiled. "They're as stubborn as you, Ari."
I blushed. He just laughed. "I remember when we first met. You were definitely something."
I laughed. "I wasn't that bad, was I?"
Just then, Sam and Dean came back. Dean was wearing his usual scowl. He looked directly at the Doctor.
"I'll listen. But if you're lying, I'll kill you."
I shot up and didn't even think about what I was thinking. I punched Dean in the face and yelled at him to shut up.
Dean regained his composure and just stared at me.
"For years I have listened to you ridicule me and put me down just because I wasn't as good as you!" I yelled at him. "I'm not the best hunter and I'm not your sister, but I am your cousin. And the Doctor is still my best friend. He took me in when no one else would. He gave me a home and a family. He's the reason I'm not dead today. If he hadn't been there for me, who knows where I would be." I took a deep breath. "Can you just, for once, listen to someone and actually understand what they're saying without having a second intention to kill them. I know you've considered killing me before."
Dean's eyes widened. Sam looked at him harshly. I sighed and felt tears on the brim of my eyes. "Please, Dean, you're like my older brother. I look up to you to protect me. Please, just listen to the Doctor. He's not the enemy. And he's saved your butt more times than you can count."
Dean stared up at me and stood up. I expected him to hit me. Dean did something unexpected. He wrapped his around me and hugged me. I cried in his chest and he just held me. After I let everything out, he pushed me to arm's length and sighed. He smiled at me.
"Alright, Ari, I'll listen." He turned to the Doctor. "Whatever you have to say, I'm all ears."
