"I think it'd be really cool to have a young Clark Kent on the show," the actor said in an interview with IGN. "To have a 15-year-old Clark Kent. I know in Batman v Superman they played it like Metropolis and Gotham are twin cities, so it wouldn't be that hard to take a boat ride over for Clark..."

As for how the show could start referencing a young Superboy, Mazouz had an idea. "You know, Clark Kent as a teenager saves a busload of kids from drowning, right?" he said. "It would just be really cool to just start a scene in the GCPD and just pan, like start on a newspaper that says, '15-Year-Old Boy in Metropolis Saves Busload of Kids From Drowning.' And then just pan up and have a regular scene that has nothing to do with the ... throw a little hint."
