I agree with you on context. I thought it would be more effective for you to experience the song in its entirety. Quoting the last line without the rest of the song would be like trying to get laughs by telling nothing but a joke’s punchline.

Finally, she began to believe in me
to see that her heart could heal
to smile in her sleep, to laugh real deep
to finally be free of the Faithless One…
— I have no idea who wrote this, I wish I did

You are the worst.

That last line totally makes the song! As I was watching the video I kept say, “Oh Josh you are protesting too much” and then he pulled it out in the end.

This is one of those lyrics that in context is brilliant, but on it’s own is kind of blah, you know? You need the story that comes before to see the brilliance.
