Cooper: After you kids came along, your mom, she said something to me I never quite understood. She said, "Now, we're just here to be memories for our kids." I think now I understand what she meant. Once you're a parent, you're the ghost of your children's future.
Cooper: Come on, TARS!
Brand: Goodbye TARS.
TARS: Good-bye Dr. Brand. See you on the other side Coop.
Cooper: See you there slick!
Cooper: Did it work?
TARS: I think it might have.
Cooper: How do you know?
TARS: Because, the bulk beings are closing the tesseract.
Cooper: Don't you get it yet, TARS? They're not *beings*... they're us! What I've been doing for Murph, they're doing for me, for all of us.
TARS: Cooper, people couldn't build this.
Cooper: No. No, not yet. But one day. Not you and me, but a people, a civilization that's evolved beyond the four dimensions we know.
[the tesseract closes around him in a brilliant flash of light]
Cooper: What happens now?
[he sees the Endurance on its flight through the wormhole, touches Brand's hand through the space-time distortion]
Cooper: Disengage Endurance Two
Cooper: Everybody ready to say goodbye to our solar system?
Romilly: To our galaxy.
Cooper: Get the patch kit.
Young Tom: How am I supposed to patch it?
Cooper: Figure it out. I'm not always gonna be here to help you.
Cooper: Hey TARS, what's your honesty parameter?
TARS: 90 percent.
Cooper: 90 percent?
TARS: Absolute honesty isn't always the most diplomatic nor the safest form of communication with emotional beings.
Cooper: Okay, 90 percent it is.
Cooper: If we find a home, then what?
Cooper: I'm coming back...
Young Murph: [crying] When?
