Please don't ask my mother for her opinions.
Stefan
You heard that?
Yeah. I've got superhearing. I hear everything.
Stefan
Only when you listen. Why?
Stefan
Why do you have a thing for me?
Stefan
Ok. Um... Why did you have a thing for me?
We said that we would never talk about this again, so just...
Stefan
Look, Caroline, please just talk to me. Tell me how, tell me why. Please just make me understand how it is that I missed it.
What kind of a stupid question is that? Why did I have a thing for you? I don't know, Stefan. Maybe it's because I thought you worth having a thing for, because when I woke up as a vampire you told me that I would get through it and I did, because when I watched Elena move on with your brother I couldn't imagine why she would let anyone like you go, because you were practically my best friend, because I trusted you.
Stefan
I'm sorry. I'm sorry for not seeing it, I'm sorry for not...
Stefan
No. I didn't say that. I... I... Look. I don't know what I felt. You know, my head was all over the place, but I am incredibly sorry for the way that I treated you.
Yeah. Well... I know what you felt, Stefan, because even if just a little tiny piece of you felt for me what I was starting to feel for you, you wouldn't have walked away, and I don't hate you for that. I don't hate you for mourning your brother, I don't hate you for being the biggest jerk on the planet while doing so, and I accept your apology.
Stefan
But you do still hate me.
Yes. Yeah, I hate you because if I don't hate you for ruining our friendship, then I have to hate myself for ruining it, and I think that I deserve better than that.
Are you seriously going to sit here and argue with me about who needs this redemption more?! You're not responsible for Enzo, Stefan!
Stefan
You keep saying that, but you're wrong. We're all responsible for our own actions. Every drop of blood that I've spilled, I am accountable for.
Then I'm accountable too, and I've spilled even more!
Stefan
Damon, I'm human. In 60 years, I'm gonna be old, I'm gonna be dead. You have quite literally an eternity with Elena ahead of you.
Which means a lot less without you.
I love you, little brother.
Stefan
I love you, too.
[Damon grips Stefan by the shoulders]
And you're right. You are human...which is why I can do this. [Damon begins compelling Stefan] Go.
Stefan
[Struggles] No, Damon, don't...
[Continues compelling Stefan] You're gonna walk out of these tunnels, and you are not gonna stop until my death breaks the compulsion. Because I am the big brother. I'm sorry I wasn't better at it until now. I said go. GO!
Stefan
Hi
Hi. [Pause] What happened? Why am I here right now?
Stefan
I don't know about Bonnie, but Damon...Damon wanted to sacrifice everything to save you, to save this town. He was ready. I'm human now. He compelled me to leave. But he should have known better. I would never walk a day on this Earth as a human without taking vervain.[Flashback shows Stefan removing blood from his arm with a syringe]
[Flashback of Damon and Katherine standing in the tunnel, Damon holding the bone dagger to her chest]
Not long now, demon spawn. I can hear that fire coming back this way.
[Struggling against Damon] You love this, don't you?
[Stefan stabs Damon in neck with syringe. Damon grunts in surprise and stares at Stefan]
Stefan
I gave him my blood. The cure.
Stefan
[Flashback showing Stefan shoving Damon safely into the room off the tunnel] Without the cure, I'd start to age. I'd be dead soon enough.
Stefan
He's okay.
[Gives a sob of relief, then realizes...] But...you, you're...
Stefan
I did what I had to do.
[Flashback shows Stefan grabbing Katherine and the bone dagger. The roar of the hellfire can be heard returning]
No! No...Stefan, please...
Stefan
Burn in hell. [Stabs Katherine with bone dagger. He looks over at Damon] Good-bye, brother.
Stefan
Tonight I saw a side of Damon that I hadn't seen in a while. The older brother I looked up to. The son who enlisted in the Civil War to please his father. The Damon I knew when I was a boy. I wanted that Damon to live. And I wanted you to have an opportunity to get to know him. He's the better man. He's the right man. It's good to see you, Elena. One last time.
