Once upon a time [Season 1, Episode 20]

Your life must be filled with such incredible loneliness if your only joy comes from destroying everyone else's happiness.

— You don't want to believe. After everything you've seen, why can't you just do it?
— Why is it so important to you that I do?
— Because I, the town... everyone needs you.
— I don't want them to need me.
— Well, that's too bad, because we all do.
— You're saying that I am responsible for everyone's happiness? That is crap! I didn't ask for that! I don't want it!
<...>
— Well, that's too bad, Emma, because that doesn't change the truth. You are our only hope.
— Then you're all screwed.
