Kryptonsite is reporting that Kyle Gallner will return as Bart Allen in the May 14 season finale of Smallville, “Doomsday.”
This version of Bart originally appeared in the fourth-season episode, “Run” (2004), in which he was billed in advertisements as The Flash, then returned for the sixth-season episode “Justice” (2007). This time he was working with Green Arrow, Aquaman, and Cyborg, forming the beginnings of what would one day become the Justice League of America. His teammates gave him a different code-name, though: Impulse.
According to Kryptonsite, Justice Leaguers Green Arrow and Black Canary will also appear in the episode, along with Cosmic Boy of the Legion of Super-Heroes. Which reminds me, I really need to get around to watching the Geoff Johns-scripted LSH episode sometime. I wonder if Smallville is on Hulu or something.
