Barry: You tortured that guy.
Oliver: I interrogated him.
Barry: When my friends said that you were a criminal, I defended you because I thought you were supposed to be a hero. I thought we were supposed to be better than them.
Oliver: Barry, you live in Central City, where it's sunny all the time and your enemies get cute nicknames. You're not in Central City. I live in the city where my best friend was murdered. Where a woman I loved was shot full of arrows and sent tumbling off of a rooftop, where my mother was murdered right in front of me, so before you...
Barry: My mother was murdered right in front of me, too. But I don't use my personal tragedies to just torture whoever pisses me off.
Oliver: Well I'm sorry, Barry, but I'm not as emotionally healthy as you are.
