Supergirl, Season 4

Brainy:
By George, I think we've got it. We stumbled upon your core trauma, James. And surprisingly, it isn't a Lex Luthor murder attempt. It's your father's death.

James:
Brainy, you said that whatever I saw in your mind palace was gonna be based on real memories. I wasn't at our father's funeral.

Brainy:
Yes. You were. Incontrovertibly.

Kelly:
No, Brainy, he wasn't. I was alone. That is not something you forget.

Brainy:
Consider the possibility that James was there, and you, Kelly, did not see him.

James:
I was across the street. At a diner. I got locked in the bathroom and nobody could hear me. By the time the manager opened up the door, his funeral... his funeral was over.

Brainy:
Perhaps that is merely a picture of the truth that got framed and hung in your mind. An excuse you invented that, over time, even you came to believe. The mind will play tricks to protect itself. Think of memories like a watercolor. While you're painting, the colors blend into each other without clear borders until they grow opaque. Once the painting dries, the picture is set.

Kelly:
Yeah, I'm sorry, I need a break.
