Charles Foster Kane:

I can see you. I know who you are. I watch you… I KNOW. I am what you see. I am what you watch. I am it. I am the hands. I am the feet. I am the eyes. I am the body. I. AM. ROSEBUD. ROOOOSEBUUUD… THE WATCHER. THE FEAR. THE ETERNAL. THE SAINT! You are nothing.

Thompson:

Mr. Kane was a man who got everything he wanted and then lost it. Maybe Rosebud was something he couldn’t get, or something he lost. Anyway, it wouldn’t have explained anything… I don’t think any word can explain a man’s life. No, I guess Rosebud is just a… piece in a jigsaw puzzle… a missing piece.

Citizen Kane, 1941.
