Season 5 (Supergirl)

"I know it can be addictive, to live in a perfect place where nothing hurts. But that's not reality. We all get hurt. But it's only by going through that pain that we're able to appreciate the good. Pain is what helps us grow. Without it, we'd never be able to... to evolve, to overcome. To forgive. Each of us came here because we're afraid. I'm afraid of getting hurt, just like you. And I do everything I can to escape pain, just like you. But the cost of escape is too great. We have to wake up now. We need to end the simulation once and for all. I believe in you."
