Both the base game and Left Behind DLC in The Last of Us Part 1 feature deep character interactions, and you can experience the full extent of it by making sure Joel and Riley talk to Ellie whenever they get a chance. The optional conversations from The Last of Us: Part 1 and The Last of Us: Left Behind will unlock the ‘I want to talk about it and ‘BFFs bronze’ trophies, respectively.
Engaging in these optional conversations in TLoU Part 1 gives you a background about the post-pandemic world and unlocks tags. Every time an optional conversation is available, you will notice a triangle button appear on the screen. When it appears, press it to start the discussion.
