Robbie Kay says he has “no idea” whether Heroes Reborn will be cancelled or renewed for Season 6, but admits he would “love to reprise [his] role” if the franchise did continue, per IGN:
I would love to reprise the role if the opportunity presents itself, because this has been a really, really cool journey and a really cool character study. It’s been such an arc with Tommy, and so much goes on. It’s almost like I’m playing two different characters sometimes, with him in the past and him in the present. You’ve seen in episode 8 now that there’s two different personas to him. There was the younger, confident Tommy who knew what he was doing, as opposed to the awkward Tommy who really didn’t know what he was doing, because such a huge part of his life was missing in his mind. So it’s been really, really cool to explore that.
