Showrunner Craig Mazin tells IndieWire about adapting one of the most important scenes in 'The Last Of Us Part II' to the HBO series.

In both The Last of Us Part 1 and Part 2, spores have always been a key part of the narrative. Whenever anyone but Ellie descends into a heavily infected zone, they put on a mask to make sure they don't get exposed. However, this is the first time it's been introduced in the adaptation.

On Sunday's episode of "The Last of Us," the show's timeline retreats to a moment of reconciliation between Joel and Ellie before this season's vengeful quest.
