"You know, before Bracken was killed, he told me you'd never be happy just being my wife. Please do not tell me that son of a bitch knew you better than I do."

Rita: "Get in."
Kate Beckett: "No. No. Not until you tell me who you are."
Rita: "You can call me Rita. I'm Castle's stepmother."

"Castle, just shut up and kiss me."

Rita: "I've been married to Castle's father for almost ten years."
Kate: "Jackson never mentioned being married."
Rita: "Well, of course not. It's classified. In this line of work, you make a lot of enemies. Attachments are liabilities, leverage to be used against us."
Vikram: "Sounds romantic."
Rita: "It can be. Absence doesn't always make the heart grow fonder, but it sure does wonders for the libido."

Rita: "William Bracken was just killed in prison. This changes things. I'm afraid the only way that you and Vikram are gonna be able to stay alive is if you go on the run. And one day, I hope I will be able to root out the big bad and get the target taken off your backs."
Kate: "'One day'?"
Rita: "Yes, dear. I'm afraid the life that you were living yesterday is over."

Allison Hyde: "Are you currently in contact with Captain Beckett?"
Castle: "No."
Allison Hyde: "But she did rescue you last night."
Castle: "Yes. And then she left me, so it's kind of a sore subject."

Castle: "Beckett, this is Hayley. She's the one who helped me find you."
Kate: "Thank you for taking care of him."
Hayley: "Yeah, it's a lot of work. I don't know how you do it."
