Lee navigates through zombie-infested sewers and finds Chuck's corpse being eaten by the zombies, realizing that the man took his own life after being cornered. As he explores further, Lee stumbles into underground shelter connected to the morgue where he finds a group of survivors led by an elderly doctor named Vernon. After a tense introduction due to Lee's intrusion, Vernon explains that his group consists of the cancer survivors whose illnesses are currently in remission and who were previously kicked out of Crawford due to their group containing sick and elderly people. Lee asks for Vernon's help getting back to surface due to the sewers' confusing layout with the man agreeing and eventually following Lee back to the house where the group plus Molly is still hiding out with Clementine missing and Kenny drinking in despair due to his escape plan having failed. Upon being asked to, Vernon agrees to treat Omid to the best of his abilities, noting that he will need antibiotics to survive the infection festering in his leg while Lee searches the house for Clementine, eventually finding her in the backyard where she reveals to have found a functional and whole boat in the garage. Upon seeing it, Kenny immediately starts to check it, eventually telling the group that while boat is seaworthy, it will require fuel change and a new battery before it can be used. As they discuss their next course of action, survivors realize that the only place in Savannah that has both the medicine required for Omid's recovery and the fuel and battery for their boat is Crawford community, deciding to perform a covert break-in and steal what they need due to Vernon's warning that the community residents won't be open for negotiation. As the result, all adult survivors including Ben and Vernon's companion named Brie prepare for the raid in Crawford while Clementine is armed and left behind to watch over ailing Omid. Eventually, group infiltrates Crawford via sewers. However, as they get there, they quickly realize that the community is somehow full of zombies who quickly end up forcing the group into the nearby school building where community resources were kept. As they bunker down in one of the rooms within the building, group separates into several teams who are sent after resources needed by the group; Christa and Vernon head into the infirmary to find the medicine for Omid, Kenny and Brie head into maintenance building to look for fuel and Lee and Molly head into nearby garage in order to secure the boat battery while Ben is left behind to try and break into the armory connected to the room. Eventually, while heading towards the garage, Lee witnesses Molly brutally killing one zombie dressed in medical scrubs but she refuses to explain her actions. After two break into the garage, they accidentally attract a large zombie horde and are forced to escape via skylight after securing the battery from one of disused cars. Upon returning to the school building, Molly takes the battery before going back out to "take care of something", claiming that she wants to hold onto it to ensure that she won't be left behind by Lee's group...
