Vegeta in “Unfinished Business”

(to himself) You let me go. I couldn't believe it. I thought it was the act of a sentimental fool. But later I realized that being spared by you was worse than dying, Kakarot. Because now, I couldn't get you out of my mind! I had to live with you every second of the day. That one act challenged everything I'd ever believed in. Everything that I'd every known. You were unraveling my reality from the inside out.
