The Vampire Diaries, Season 5

Damon:
Katherine didn't do this. I did. I thought you broke my heart, so I ripped open Aaron's neck - that is how much control you have over me.

Elena:
And I'm still here. That's how much control you have over me.

Damon:
Listen to us! This is toxic! We are in a toxic relationship, Elena. I just killed your friend and you find someone else to blame!

Elena:
You want me to blame you? Easy. Done! You screwed up Damon. Again.

Damon:
Thank you!

Elena:
You put me in a position where I have to defend you, again. Where I have to bend my morals, again. Where I have to go against every single thing that I believe in, again, 'cause I love you!

Damon:
Well then stop loving me!

Elena:
I can't!
