The Last of Us Season 2, episode 6 broke our hearts in myriad ways both overt and subtle. Spotted by Redditor Unwept_Skate_8829, there's a costume inclusion in the episode's opening scene that includes a deeply important object to the series: Joel's watch.

It was just the two of them alone with a guitar and a song.

Both in the game and in the show, Joel singing this song seems to speak to his devotion to Ellie.
