Mika hiding behind a tree. As the group recomposes themselves, they hear screaming in the distance. Tyreese leaves the girls, saying he has to go investigate and they need to keep an eye on a crying Judith. Lizzie covers Judith's mouth to muffle her cries. A pair of walkers nonetheless begins to close in. Mika attempts to warn her sister, but as Lizzie is quieting Judith she begins to slide her hand up over the baby's nose as well, becoming increasingly lost in the moment.

After Bob says they'll do it together, and Sasha reluctantly agrees, Sasha opens the emergency door with the intention of allowing one walker to exit at a time. Eventually, the press of walkers trying to exit the bus proves too much, and Sasha can no longer hold the door. As the walkers attack, Bob and Sasha are forced to defend themselves. Maggie initially seems dazed, and is nearly
