Mac Taylor and Quinn Shelby

QUINN SHELBY I still have a thing for you. Why didn't you ever call me?

MAC TAYLOR Quinn, I was married.

QUINN SHELBY It was just a kiss, Mac. I know... a moment of weakness.

MAC TAYLOR  It was a mistake. I loved my wife.

QUINN SHELBY  Don't I know it? Every day I worked alongside you, you never let me forget that.

MAC TAYLOR  It wasn't my intention to make things difficult.

QUINN SHELBY  You know, I've thought about this moment so many times, about what I would say to you when I finally got the chance. And here I am, and all I keep thinking is... does he ever wonder what if? Why I hate her every day a bit more?
