If you watched The Flash and were wondering who that bloke looking a lot like Stephen Amell was, well it probably was him, because he appeared in a few episodes. But then if you were still watching and wondered who that other bloke looking a lot like Stephen Amell was, it was his cousin Robbie, who plays Ronnie/Firestorm on the show. The pair bear a rather close family resemblance, and did finally get the chance to share the screen during the penultimate episode of The Flashs first season, Rogue Air. They were quite close growing up, and in Robbies words were phenomenal at playing beer pong together. Maybe an idea for a future crossover?
