Brooke: "They like it when I drive, so I drive. It's funny, I grew up in Tree Hill, I spent most of my life here, but it wasn't till my sons were born and I couldn't sleep that I really got to know this place. That use to be my view of tree hill at 2am, well my partial view. Now this is my view. We drive through the same streets I drove in high school and listen to the same music, at least when we can agree. Sometimes we try the 80′s, sometimes classic rock, Sunday Lane works for all of us. 2am, 3am, 4. We drive, and we think, and we fuss a bit. Sometimes we eat, well I eat. I guess some people might let it wear on them, the lack of sleep. But I don't mind it really. I like tree hill like this. I like my car like this; warm, safe and loved. It's what I wished for, mostly."

"Do you know what it's like to have a beautiful granddaughter and have no expectations of holding her? Or to accept that you'll never be a part of your son's family? Either son, I know what I've done. I know what I've created. I just need a little help."
Dan Scott to Haley.

"I sleep better knowing that your side of the bed is closer to the door, because if somebody breaks in then, they are probably going to brake in and get you first and I can run, ok?"
"You say the sweetest things to me Haley James."
"I just miss you, I want you to come home. I feel spoiled when you are here."
"Well prepare to be spoiled because I'm going to be home tomorrow night or the next day depending on these flights."
"Really? That just made my heart race."
"Mine too. Now you take that feeling and you go back to bed ok? I'll be home before you know it."
"Ok, I can't wait. I love you Nathan."
"I love you too, sweet dreams."
Haley James Scott and Nathan Scott
