Having found the keys to the drugstore, Lee and Lilly break in to get the medications that they need, unintentionally setting off the alarm and alerting the entire group of walkers within the area. While Kenny rounds up the rest for the survivors to escape; Lee, Doug, Clementine and Carley were left to hold the walkers back. She takes on a broken window with her gun while Doug takes another, leaving Lee to hold the door on his own. At this point, Carley runs out of ammo and is mauled by a pair of walkers while Doug is grabbed by a pair of walkers and left defenseless which forces Lee to choose either one of them, choosing Carley results in Doug's death and vice versa.
