Sydney: (About Irina) You were right to investigate her.
Sydney: No, it's okay. It's the truth. I'm not blaming you, it's me. I was so naive about her.
Vaughn: I don't think you should be a part of this task force. Look, you know how I feel about Irina Derevko but no one should have to hunt down their own mother, no matter what the circumstances are.
Sydney: She was never my mother.
Vaughn: Do you want to believe that?
Sydney: Don't do this to me again, don't condescend me.
Vaughn: It's not what I'm doing, you know that, but if you corner her and you hesitate to pull the trigger, even for one second, it could cost you your life. (Sydney puts her glasses and ear plugs back on)
Sydney: I won't hesitate.
