Behind the scenes

 * In the DC multiverse Barry Allen is the second person to take up the superhero mantle of The Flash.
 * Barry's appearance in the second season's twentieth episode is said to focus more on his world, and hopefully act as a backdoor pilot for a Flash pilot. However, it was reported on November 18, 2013 that episode 20 would no longer act as a pilot, and a Flash pilot would automatically go ahead. Due to this, it remains unclear as of yet if episode 20 will still revolve around or even include Barry.
