Kate and Nick in “Two of Hearts”

Look, I'm sorry I'm Immortal, Nick, there's nothing I can do about it.

Now you're getting irrational.

Tell me it doesn't drive you crazy, that I can't die and you can.

I don't believe this! I mean, first you lie to me, and then when things don't work out you lay this on me.

Look, you knew what I was when we met. You know the Game, you know the Rules.

And you know me, Kate. Am I the type of guy whose going to sit on his ass and let you walk off and maybe get whacked? Tell me Kate, is that who you ever thought I was?

No.

How the hell did we happen?

I didn't know we were going to happen. I didn't know I was going to fall in love with you. Nick, the part of my life that has to do with being Immortal has nothing to do with you. It can't.

Katherine, I'm either in your life, all of it, or I'm gone.
