The Last of Us Season 2 is mostly about Ellie, Abby, and the often-futile drive for revenge. Isaac was played by Jeffrey Wright in The Last of Us Part 2, but his role was much smaller. It’s not until the last third of the game that we actually see him, fresh from torturing a Seraphite member. While Isaac doesn’t talk about his backstory, a close look at the documents found in the game reveals he never worked for FEDRA. Much like in the game, he’s torturing a Seraphite, but instead of meeting him just as he’s leaving the room, we see the full interrogation in detail.
