Young Mazino is such a cool customer that even dropping a (sort of) spoiler for The Last of Us Season 2 while on The Tonight Show barely phases him.

In the clip above Jimmy Fallon asks the actor to set up what's happening on the HBO adaptation this season, to which he responds: "Well, the two main characters, Ellie and Dina, are in a war zone trying to enact their revenge, because Pedro Pascal's character Joel got viciously murdered by somebody from the WLF..."

That's about as far as he gets before Fallon cuts in with a "spoiler alert", and Mazino is forced to sheepishly apologise to the audience.

"Sorry I'm new to this whole thing, I assumed everybody here had watched the show," he grins. "Let me take that back. I'm just kidding. None of that happens."

In his defence, it's been a good few weeks now since that episode.
