Jack Bauer asks Renee Walker to join his assault team since he needs every experienced agent he can get. He warns her to be careful and promise she’ll be okay. How sweet!

Jack Bauer: I want all of you to silence your weapons. The only way this operation works is if we take these terrorists by surprise. If they get a sense that we’re moving in on them, President Hassan is dead. I don’t have to tell you what we’re up against, and the significance of this operation. Trust your training and let’s get this done. Check your comms, we’ll meet at the rally points in two minutes. Renee, I need to talk to you.
Renee Walker: Yeah?
Jack Bauer: I want you with me on the assault team.
Renee Walker: I thought you wanted me running ops?
Jack Bauer: In order for this to work, I need every agent with experience I can get. But you need to understand, this goes against every instinct I have. So you need to promise me that you’ll stay right behind me and you’ll do exactly as I say.
Renee Walker: Okay.
Jack Bauer: No, I need you to promise me.
Renee Walker: I promise.
Jack Bauer: Get ready.
