Ultron: Did you know this church is in the exact center of the city? The elders decreed it so that everyone could be equally close to God. I like that. The geometry of belief. You're wondering why you can't look inside my head.

Wanda Maximoff: Sometimes it's hard. But sooner or later, every man shows himself.

Ultron: I'm sure they do. But you needed something more than a man. That's why you let Stark take the scepter.

Wanda Maximoff: I didn't expect, but I saw Stark's fear. I knew it would control him. Make him self-destruct.

Ultron: Everyone creates the thing they dread. Men of peace create engines of war. Invaders create Avengers. People create... smaller people? "Children." I lost the word, there. Children... designed to supplant them, to help them... end.

Wanda Maximoff: Is that why you've come, to end the Avengers?

Ultron: I've come to save the world. But also... yeah.
