We are all sad to see him go, but we will all be better for the many shows he will no doubt create and run in the future," The Flash exec producer Greg Berlanti said in a statement to The Hollywood Reporter. "Eric Wallace has proven his own exceptional talent and voice since season four, and we couldn't be more thrilled to watch how he shapes the future of Team Flash and the many thrilling adventures that lay ahead for our characters and dedicated fans."
