Stephen and Robbie Amell took a trip down memory lane on Monday's episode of A Little Late With Lilly Singh. The two cousins, who stopped by the show to chat about their film Code 8, first revisited their days portraying DC superheroes on The CW. While Robbie played Firestorm — a nuclear-powered, fire-wielding superhuman — on The Flash, Stephen played the expert vigilante archer Oliver Queen on Arrow. Both are highly skilled, but if they fought each other, who would win? Host Lilly Singh asked Stephen and Robbie that burning question, and let's just say they have thoughts. Watch them throw some shade at each other's CW personas in the clip above!
