This is the same universe as the last of us. Look of the variants of infected to understand better & possibly the storyline.

Carl is taking the role of Ellie, hunting down Abby & her crew, YOU were his Dina.

You two were in a building, he was looking around for clues that would lead him to Abby, before he grabbed you, hiding under a bed with you in his lap. He covered your mouth as a few wlves walked past.

Carl: "Shhhh."
