A/N: If you're a Cassie lover, please be warned there is bashing.

"Were on the road again. Yeah, yeah were on the road again!" I sang from the backseat. Boredom had set in about an hour on the road. We had already been on the road for about two hours. It was a tendency of mine to make up songs whenever I got bored. "Were on the road again!" I made a popping sound with my lips and gently hit both Sam and Dean in the head as if they were my drums.

"If you don't shut up, I am going to throw you out of the car." Dean said glaring at me from the rearview mirror. I childishly stuck out my tongue at him and leaned back into my seat.

"Okay, I think I found a way we can bypass that construction, just east of here. We might even make Pennsylvania faster than we thought." Sam said looking at map from shotgun. There was construction all over where we were driving. Dean was getting irritated with it and was about to lose his temper.

"Were not going to Pennsylvania anymore." Dean shifted in his seat a bit.

"What do you mean were not going to Pennsylvania anymore?" I asked leaning up between the two of them.

"I mean were not going there anymore. How many different ways do I need to say it?" Dean didn't take his eyes off the road. There was something he wasn't telling us.

"Why not?" Sam asked folding up his map. Dean sighed.

"I got a call from an old friend." Old friend? She? There was only one old friend in Dean's life that was a girl. God Dammit.

"Were going to see Cassie aren't we?" I asked meeting Dean's glance from the rearview mirror.

"Who's Cassie?" Sam asked. We ignored him.

"Maybe." Dean answered vaguely.

"Dammit Dean, after everything she put you through." I nearly yelled at my brother.

"Listen, she wouldn't have called if she didn't need our help." Dean turned off on the highway.

"Who's Cassie?" Sam asked again looking between the two of us.

"Dean's ex-bitch." I spat bitterly. I leaned back again crossing my arms over my chest. Dean rolled his eyes at me.

"She was my girlfriend." Dean explained to Sam.

"Girlfriend? Like you actually dated her? For more then one night?" Sam let out a surprised laugh.

"Is that so hard to believe?" Dean asked trying to sound offended.

"Well kind of." Sam answered. "So why are we going to see her?" My ears perked up at that question. Why were we going to see Cassie?

"Her father was killed last night. Truck hit him or something." Dean explained to the both of us.

"That's too bad about her dad but why would she call us?" Sam asked taking a quick glance out the window. I cocked an eyebrow at Dean.

"Dean, tell Sammy why Cassie would call us." I taunted him. Sam looked back at me. I raised my eyebrows at him. Sam quickly snapped his attention back to Dean.

"You told her!" Sam yelled.

"Yup Sammy he did. Family rule numbero uno, we do what we do and shut up about it." I saw Dean purse his lips together.

"You told her!" Sam repeated. Dean stayed quiet. "Dean!" Sam yelled louder.

"Looks like it." Dean mumbled running a hand over his mouth. Sam shook his head obviously upset. I could tell what he was thinking. He had lied to Jessica the whole time he was dating her and Dean dates a girl and spills his guts.

"It's alright Sammy, I was upset about it too." I patted Sam's shoulder, while glaring at Dean.

Neither Sam nor I spoke to Dean for the rest of the ride. Sam was pissed because Dean told Cassie our family secret and I was pissed just because we were going to see Cassie. We pulled up to Cassie's house to see her waiting outside for us. Dean turned so he could face me.

"You better be nice." He hissed at me. I cocked my head at him and rolled my eyes before getting out of the car.

"Hi Dean." Cassie greeted awkwardly. She nodded in acknowledgement toward Sam. She turned her glance to me. "Aidan." I could tell she was trying not to be nasty to me. She probably disliked me as much as I disliked her. It probably didn't help that I left her about fifteen nasty voicemails after her and Dean called it quits. No one breaks my brother's heart and gets away with it.

"Cassie." I greeted through clenched teeth. I mustered up my best fake smile. Dean introduced Sam to Cassie and we all made our way into the house. Once inside Cassie proceeded to tell us about her dad and the trunk. She told us that his friend died the same way. There was something about a dent and no tracks. I don't know I wasn't really paying attention. My attention kept focusing on the random knick-knacks around the house. At one point her mom came home but quickly left. I found that a little suspicious but since she just lost her husband I let it go.

After we left Cassie's we found a motel and got ourselves a room. I volunteered myself to go get food. Upon coming back I noticed Sam sitting on a swing in the playground that the motel had. Curiosity got the best of me so I went over to him.

"This swing taken?" I asked gesturing to the empty swing.

"Nope." Sam answered staring at the stars. I set down the food and sat on the swing. "Cassie seems nice enough." Sam said giving me a quick glance. I started to gently rock in the swing.

"Ah yes. She seems nice enough until your dumbass big brother tells her your family secret." I pumped higher.

"She didn't take it well?" Sam scrunched up his face.

"I think she used the words, like insanity and mental institutions." I heard Sam laugh.

"Is that why you hate her?" He asked beginning to rock in his own swing.

"I hate her because she broke Dean's heart after he told her what we did. He trusted her and she just ripped the rug out from under him. I had to deal with his moody ass for a month." I stopped swinging letting my feet drag on the ground. "I have never seen him so heart broken before." I came to a complete stop. "So why are you out here?"

"Just thinking." Sam replied drawing designs in the dirt with the toe of his shoe.

"About?" I pushed.

"Jess." Sam said sadly. I bit the inside of my cheek trying to think about what to say. "I never told Jess about our family secret. I was never going to. I thought I was protecting her that way."

"Sure. Sounds reasonable to me." I tried to sound supportive of his choice on not telling Jess. Sam shook his head.

"I sometimes wonder though, maybe I could have protected her more by telling her." I tried to hide my confusion.

"What do you mean?" I asked wondering where Sam was going with this.

"She would have been more prepared maybe, I don't know." Sam's voice trailed off.

"Sammy…"

"I dreamt about her death." Sam's voice was just barely a whisper. I strained to hear him.

"I know. I have many sleepless nights to account for it." I gave him a small smile.

"I dreamt about it before it happened." Sam dipped his head so his hair was covering his eyes. My eyebrows popped up in surprise. "I thought they would just go away. So I didn't tell anyone about them. I just wanted to be normal. If I just would have told Jess about our past, then I could have warned her about my dreams and I could have saved her." My heart ached for Sam. I knew he blamed himself for Jessica's death but I never knew how bad it actually was.

"Alright Sam listen to me." I said sternly. "You can't blame yourself for Jessica's death. If you want to blame someone, blame Dean and me. We were the ones that took you away from her."

"I don't blame you guys." Sam's voice was a little louder but not by much. His head still hung in his hands. I took a firm hold of his chin and made him look at me.

"Well you can't blame yourself. If you want to blame someone, blame that evil son of a bitch that killed her." I soften my voice. "Sam there was nothing you could have done to stop it."

"I could have warned her." Sam jerked his head out of my grasp.

"It still would have happened." I whispered making him listen to me. Sam leaned his head back choking back tears.

"I know." He racked a hand though his hair. "I know it would have."

"I know you loved her and you would have done anything to protect her but there is nothing you could have done." Sam seemed to accept my response.

"Do me a favor? Don't tell Dean. He worries enough as it is." I thought about that for a minute. I had a terrible time of keeping secret from Dean. I told him everything. Somehow Dean always knew when I was hiding something from him. Like the time I didn't tell him it was me who stained his favorite T-shirt as a kid or like how he knew when I had my first boyfriend. Sam looked at me desperate for me not to tell him. I traced my teeth with my tongue still thinking about Sam's request.

"Of course." I finally gave in to Sam's puppy dog stare.

"Thanks Aidan." Sam gave me a half smile, which I returned.

"No problem Sammy." I got up, gathered the bags of food and squeezed Sam's shoulder as I walked by him.

A/N: Hm these two seem to be getting along real well lately. It almost seems time for them to fight again. Later chapters though. Next Chapter: Dealing more with the whole Route 66 episode. Dean knows that Aidan is hiding something and he is determined for her to tell him.
