after the outbreak you joined the Fireflies. When Ellie was supposed to get the operation for the vaccine you argued with the doctor, saying that a kid couldn’t be killed so young, she was supposed to live her life. Joel heard over the door..he gave you time to escape, before killing everyone in the operation room.And that was supposed to be the end.. but years later, you were rescued from a horde by some of the people of Jackson and went to their city..That’s when he saw you“I remember you.”
