Bonnie: Do you have any idea how long three seconds are in a life or death situation?

Damon: In the first second, I thought how amazing it would feel to have Elena back in my arms again.

By second number two, I kissed her.

And by the third, I remembered that you are my best friend and that if anything ever happened to you I would lose my mind.

So yes, Bonnie. I do know how long three seconds are.
