...and they lived happily ever after.

Meredith:  You just couldn’t trust me.
Derek:  Why should I ever trust you?  Why should I trust you?  You ended my trial, you set back my career, you nearly ended your own, you destroyed Richard’s.  I have no reason to trust you!
Meredith:  Well, then, why are you with me?
Derek:  Because of that!  Because I meant that!  I promised I wouldn’t run.  I promised I would love you.
Meredith:  Even when you hate me.
Derek:  Even when I hate you.  I’m trying, Meredith.  I’m trying, but you make it so damn hard.
Meredith:  I understand, and I don’t want you to keep the promise, not if you don’t want to, and not if you can’t trust me with our daughter.
Derek:  I do, I trust you with Zola.
Meredith:  Well, you just said—
Derek:  That’s not what I said.  I know that you took her to protect her, I know you altered the trial for Adele and for Richard.  You stood in front of a bullet for me.  I know why you do all of it.  It’s what I love about you.
Meredith:  And what you hate about me.
Derek:  Yeah.
