It's My Party and I'll Die If I Want To

This episode marks the end of Interlude IV. "Do you think I'm... I'm doing enough... with my powers, with my time here? Well, Barry, you tell me. Do you give people hope? Are you moving through your city like a... guardian angel? Do you make a difference? That bolt of lightning chose you. Don't ever forget it."

- Barry Allen and Oliver Queen
