Optimus Prime : How many more of my kind must be sacrificed, to atone for YOUR mistakes?
Cade Yeager : What do you think being human means? That's what we do. We make mistakes. Sometimes, out of those mistakes come the most amazing things... When I fixed you, it was for a reward. That was it. That was why. The money. And it was me making a mistake. Without it, you wouldn't be here. So even if you got no faith in us, I'm asking you to do what I do. I'm asking you to look at all the junk and see the treasure. You gotta have faith, Prime, in who we can be.
Joshua Joyce : Threatening a professional CIA killer. Possibly not my finest hour. I'd like to have that one back.
Darcy Tirrel : Killer? I thought they were your friends!
Joshua Joyce : No. Not friends. Business. They gave me this bomb.
Su Yueming : Bomb? Is there a bomb in the bag?
Darcy Tirrel : Yes, there's a bomb in the bag.
Su Yueming : Shit!
