[To Kelly] What Did Katherine promise you?
You don't get it, she promised me nothing- oblivion, emptiness. Anything is better than endless torture in hell. And all I had to do is to keep you idiots distracted until the fire started.
What is Katherine planning?!
You don't have to bully me, she wanted me to let you know. She's gonna burn down Mystic Falls. With hellfire. Tonight. (Chuckles)
She's talking about the bell.
Are you seriously going to sit here and argue with me about who needs this redemption more?! You're not responsible for Enzo, 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!
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.
[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.
[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!
Hi. [Pause] What happened? Why am I here right now?
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]
I gave him my blood. The cure.
[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.
[Gives a sob of relief, then realizes...] But...you, you're...
[Flashback shows Stefan grabbing Katherine and the bone dagger. The roar of the hellfire can be heard returning]
No! No...Stefan, please...
Burn in hell. [Stabs Katherine with bone dagger. He looks over at Damon] Good-bye, brother.
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.
