"See, deep down, I'm just jealous. You got friends. You could have a life. Me? I know I'm a freak. And sooner or later, everybody's gonna leave me." Dean to Sam 1.06

"Angels? I don't think so. 'Cuz there's no such thing. I believe in what I can see. In all this time I have never seen anything that looks like an angel. And don't you think that if they existed that we would have crossed paths with them? Or at least know someone that crossed paths with them? No." Dean to Sam 2.13

Dean: "Okay, all right. You know what? I get it. You've got faith. That's - hey, good for you. I'm sure it makes things easier. I'll tell you who else had faith like that - Mom. She used to tell me when she tucked me in that angels were watching over us. In fact, that was the last thing she ever said to me."

Sam: "You never told me that."

Dean: "Well, what's to tell? She was wrong. There was nothing protecting her. There's no higher power, there's no God. I mean, there's just chaos, and violence, and random unpredictable evil, that comes out of nowhere and rips you to shreds. You want me to believe in this stuff? I'm going to need to see some hard proof. You got any?" 2.13

Sam: "I wanted to believe... so badly... It's so damn hard to do this, what we do. You're all alone, you know? And... there's so much evil out there in the world, Dean, I feel like I could drown in it. And when I think about my destiny, when I think about how I could end up..."

Dean [sitting on the bed beside him]: "Yeah, well, don't worry about that. All right? I'm watching out for you."

Sam: "Yeah, I know you are. But you're just one person, Dean. And I needed to think that there was something else, watching too, you know? Some higher power. Some greater good. And that maybe..."

Dean: "Maybe what?"

Sam: "Maybe I could be saved. But, uh, you know, that just clouded my judgment, and you're right. I mean, we've gotta go with what we know, with what we can see, with what's right there in front of our own two eyes."

Dean: "Yeah, well, it's funny you say that. (...) I'll tell you one thing. If... The way he died, if I hadn't seen it with my own two eyes I never would have believed it. I mean... I don't know what to call it."

Sam: "What? Dean, what did you see?"

Dean: "Maybe... God's will." 2.13

"I always tried to protect you... Keep you safe... Dad didn't even have to tell me. It was just always my responsibility, you know? It's like I had one job... I had one job... And I screwed it up. I blew it. And for that, I'm sorry." (wipes tears from his face) "I guess that's what I do. I let down the people I love. I let Dad down. And now I guess I'm just supposed to let you down, too. How can I? How am I supposed to live with that?" (crying) "What am I supposed to do? God. What am I supposed to do? What am I supposed to do?!" Dean 2.22

Sam: "When you sacrifice to Hold Nickar, guess what he gives you in return."

Dean: "Lap dances, hopefully." 3.08

Say hello to Dean's bisexuality

"I know how dead you are inside. How worthless you feel. I know how you look into a mirror and hate what you see. I mean you're going to hell and you won't lift a finger to stop it. Talk about low self-esteem. Then again, I guess it's not much of a life worth saving, now, is it? I mean, after all, you got nothing outside of Sam. You are nothing. You're as mindless and obedient as an attack dog. What are the things that you want? What are the things that you dream? I mean your car - that's dad's. Your favorite leather jacket - dad's. Your music - dad's. Do you even have an original thought? No. No, all there is is "Watch out for Sammy. Look after your little brother, boy." You can still hear your dad's voice in your head, can't you? Clear as a bell. I mean, think about it. All he ever did was train you, boss you around. But Sam... Sam, he doted on. Sam, he loved. Dad knew who you really were: a good solider and nothing else. Daddy's blunt little instrument. Your own father didn't care whether you lived or died. Why should you?" Dean to himself in his dream 3.10

"We know this much: that every day, including today, is a new beginning. We learned more than we can say in the brutal feat. We were forced to face something far more scary than ghosts. We were forced to face ourselves. War changes man. You know, we just... ah gosh, we just like to think that you're out there, watching over us. And here we were thinking that, you know, we were teaching you and all this time you were teaching us, about heart, about dedication, and about how gay love can pierce through the veil of death and save the day. Thank you. Go well into that starry night. Go well." Ghostfacers 3.13
