Supernatural, Season 4

Dean:
Surprise.

Bobby:
I, I don't...

Dean:
Yeah, me neither. But here I am. [Suddenly, Bobby attacks Dean.] Bobby! Bobby! It's me!

Bobby:
My ass!

Dean:
Whoa, whoa, whoa, wait! Your name is Robert Steven Singer. You became a hunter after your wife got possessed... you're about the closest thing I have to a father. Bobby. It's me. I am not a shapeshifter!

Bobby:
Then you're a Revenant!

Dean:
All right. If I was either, could I do this... with a silver knife? [cuts his arm]

Bobby:
Dean?

Dean:
That's what I've been trying to tell you.

Bobby:
It's... It's good to see you, boy.

Dean:
Yeah, you too.

Bobby:
But... how did you bust out?

Dean:
I don't know. I just, uh, I just woke up in a pine box...

[Suddenly, Bobby splashes water in Dean's face. Dean pauses, spits.]

Dean:
I'm not a demon either, you know.

Bobby:
Sorry. Can't be too careful.
