Izzie: I love you. I will always love you. You own a peace of me. So, although you will be gone, you won't be forgotten. Not by me. I'm sorry we never got our chance. I'm sorry that we never... got to get married or have children, or grow old together, I wanted that so much... I want to be your wife more than anything.
Denny: Why are you telling me this?
Izzie: I'm trying to let you go so that your soul can be at peace.
Denny: But I have peace, Izzie. I'm here for you.
Izzie: Goodbye, Denny. I love you, but goodbye.
