Pay the Piper

"You gave me my world back. You'll get your world back, too. But you have to do more than just forgive yourself. You have to believe that your world can change. That's the part I'd forgotten. Thanks for reminding me."

Trivia

 * The title references the fact that Team Flash paid the piper (Hartley) by saving his boyfriend's life.
 * When Godspeed fights Barry and knocked him off, the animation of their fight is the same used in the Into the Void episode but is also completely opposite.
 * This time, the fight takes place during the night.
 * The roles of who chased and who's hunted are also reversed since Godspeed was now the one that hunted Barry instead of the other way around.
 * This episode used some archive footage from The Sound and the Fury to explain why Hartley hated Team Flash.
