In My Time of Dying

Sam Winchester: [to John] You know, you care more about killing this demon than you do saving your own son!

Dean Winchester: [as a spirit, unseen and unheard] No no no, guys, don't do this!

John Winchester: [to Sam] Do NOT tell me how I feel. I am doing this for Dean.

Sam Winchester: HOW? How is revenge gonna help him? You're not thinking about anybody but yourself, it's the same selfish obsession!

Dean Winchester: Come on guys, don't do this!

John Winchester: That's funny. You know, I thought this was your obsession too! This demon killed your mother, killed your girlfriend! You BEGGED me to be a part of this hunt! Now if you'd killed that damn thing when you had the chance, none of this would've happened!

Sam Winchester: It was possessing you, Dad! I would've killed you too!

John Winchester: Yeah, and your brother would be awake right now!

Dean Winchester: Shut up! Both of you!

Sam Winchester: Go to hell.

John Winchester: You know what? I should've never taken you along in the first place. I knew it was a mistake!

Dean Winchester: I said SHUT UP!

[Dean lashes out, knocking a glass of water onto the floor where it shatters. John and Sam look to where Dean is standing, unseen by either of them]

Dean Winchester: Dude, I full-on Swayze'd that mother.
