Carter: "I'd rather you didn't."
Edwin Jarvis: "Stark can be thoughtless. Inconsiderate. Vain. Childish. Unreliable. Arrogant."
Peggy Carter: "You flatter him."
Jack Thompson: "If you don't mind, these surveillance reports need to be filed, and you're really so much better at that kind of thing."
Peggy Carter: "What kind of thing is that, Agent Thompson? The alphabet? I can teach you. Let's start with words beginning with 'A'."
Edwin Jarvis: "Mr. Stark believed the intruder had some advanced technological assistance."
Peggy Carter: "Mr. Stark believes brushing your teeth requires advanced technological assistance."
Werner Reinhardt: "Cut off one head, two more shall grow in its place."
Peggy Carter: "Then I guess we'll keep cutting them off."
The world has changed, and none of us can go back. All we can do is our best, and sometimes, the best that we can do, is to start over.
