It was quiet again in the car. Dean was angry with Cas for threatening his baby, Sam thought he should let both Cas and Dean alone and Cas was still angry with Meg.
“Hello, Jo” Cas broke the silence.
“Cas, don’t be an idiot. Jo’s not here” Dean said.
Sam turned around. “Eh, Dean?”
“What?” Dean snapped.
“Maybe you should check your rear view mirror” Sam suggested. Dean looked in his rear view and cursed. Jo was sitting next to Cas.
“What the hell are you doing here?” Dean asked angry after he pulled over. “And how did you get here in the first place?”
“Anna gave me a ride” Jo explained. “You didn’t honestly believe I was letting you go that easy? I’m coming with you, whether you like it or not”
“And you don’t honestly believe I’m letting you come with us? I’m going to call Ellen to come and pick you up” Dean said.
“No, you’re not! I’m not a baby anymore. I can take care of myself” Jo protested. “I gave my life for you. The least you could do is show me a little respect. I’m coming with you. My mom knows where I am and she knows I can handle myself”
Dean looked at Sam for help, but it Cas who made the decision.
“She’s coming with us” he said and he telepathically started the car.
