Sarah Miller is Joel's 12-year-old daughter and the character you control at the start of The Last of Us Part I. In Hometown you walk her through the family house near Austin on the night the infection breaks out, before Tommy drives the family into the chaos.
The chapter opens with Sarah waking on the couch and handing Joel a new wristwatch for his birthday, joking that she paid for it by selling drugs. She falls asleep watching TV with him and he carries her up to bed.
A phone call from Tommy wakes her in the middle of the night and the line goes dead. As Sarah you search the dark house: the handmade birthday card in the hall, a TV news report that cuts off, an explosion in the distance and police cars racing past. Downstairs she finds Joel's phone full of missed calls from Tommy.
Tommy's car crash breaks Sarah's leg, so Joel carries her on foot through burning streets while Tommy holds the infected back at a bar.
On the highway a soldier is ordered to shoot them. Joel shields Sarah, but she is hit in the stomach and dies in his arms in the early hours of September 27, 2013. Joel never speaks of her if he can help it; Ellie only learns about her from Maria in Jackson.
Jimmy Cooper
He is the first infected you see in the game, during the outbreak night in Hometown.
Rose Graham
Rose Graham is the KATX Channel 2 News reporter Sarah watches on Joel's bedroom TV in Hometown. Her live report from downtown Austin is the first real sign that the riots are something worse.
Joel Miller
Joel Miller is the man you play for almost all of The Last of Us Part I. A hardened smuggler in the Boston quarantine zone, he takes a job escorting 14-year-old Ellie out of the city, and the drop-off turns into a year-long trip across the country to find the Fireflies.
Tommy Miller
Tommy Miller is Joel's younger brother, a former Firefly who now helps run the settlement at Jackson, Wyoming. He drives Joel and Sarah through the chaos of the prologue, and twenty years later Joel tracks him down at a hydroelectric dam in the chapter Tommy's Dam, hoping he will take Ellie to the Fireflies.
