Constantine and Sara in “Unfinished Business”

Constantine

I'm just trying to look after you, love. You and I are similar. We're both survivors, but our survival comes at a terrible cost. Look, you can take it from a man who's caused nothing but misery to everyone he's ever loved. Trust me. End it with Ava before it's too late.

Sara

You ever think that you cause misery not because of some romantic "I was born to walk alone" crap, but because you're an ass who doesn't know how to trust people?

Constantine

You know, I trust. The people around me get hurt, killed or far, far worse.

Sara

You think that I'm not scared? That I don't know grief? I'm not willing to turn my back on life, because that is exactly what you're doing, John. Our friends and family, they don't make us weaker, they make us stronger. You know what you need? You need to be a part of a team.
