Dean Winchester: I think I’ll go for a drive.

Bobby Singer: Have fun.

Dean Winchester (to the Impala): Hey, baby. (turns on the radio and “Carry On My Wayward Son” is playing…) Ah! I love this song.

(When finally it is time for Sam to join Dean in Heaven and they meet again…)

Dean Winchester: Hey, Sammy.

Sam Winchester: Dean.
