Grey's Anatomy, Season 11

Richard:
I lied to you before... About what happened that day at the carousel. I remember what she said. I remember what I said. I remember everything. It was a Thursday afternoon. We had made a pact. She would leave Thatcher, and I would leave Adele. Your mother had just received her first Harper Avery nomination. She was so excited. And I was... jealous. Not like healthy competition. A hateful, hopeless jealousy, too far ahead to catch up to. Her success illuminated everything I hadn't yet accomplished. The night before, as I worked up the nerve to tell Adele, I thought of your mother. I thought of what she could do at such a young age. I thought of what she would do. And I thought: "I will spend my life feeling like this, my entire life." So I ruined it.
