The Vampire Diaries, Season 1

Stefan:
You shouldn't be here.

Elena:
I know.

Stefan:
Now you know.

Elena:
That wasn't you.

Stefan:
Oh, it was absolutely me. A monster...a predator. It's who I am, Elena.

Elena:
That's what the blood makes you.

Stefan:
The blood brings out what's inside of me, and if you think any differently then you're an idiot!

Elena:
I know this isn't you, Stefan.

Stefan:
I wanted to drain every ounce of blood from that girl's body.

Elena:
No...

Stefan:
It's who I am, Elena!

Elena:
No, you can't scare me off.

Stefan:
Why would you risk it? Why would you come here?

Elena:
Because I did this! This is my fault! I'm the one who made you drink the blood...

Stefan:
All you did was expose me to who I really am!

Elena:
This isn't you.

Stefan:
STOP SAYING THAT! (tries to compose himself) Don't get any closer to me...

Elena:
I'm not going to let this happen to you.

Stefan:
Stop.

Elena:
Stefan, I'm not going to give up on you. I believe in you...

Stefan:
STOP! (slams her against the wall) Stop! (hits the wall behind her)

Elena:
(gasps loudly)

Stefan:
(realizing what he's done) I'm so sorry.

Elena:
It's okay... It's okay...

Stefan:
(sobs)... I don't know what's happening to me...

Elena:
It's okay, Stefan. Shhh...it's okay. It's okay. (starts crying) You're gonna be okay... (stabs him with a vervain tranquilizer)
