After Merle let Michonne walk away from Woodbury, she left him a gruesome message composed of decaying zombie body parts: GO BACK. Acting on the Governor's orders, Merle was dead-set on killing Michonne and bringing her head back as a trophy. But Michonne got the drop on Merle and his henchmen, hurling herself out of a tree, ninja-style. In the ensuing fight, Merle put a bullet in her leg. But Michonne beheaded two of his henchmen with her power katana and managed to escape with the tried-and-true method of covering herself with zombie guts. As walkers approached the scuffle, Michonne disemboweled a zombie by plunging her sword straight into his abdomen. We watched in horror as greasy, grimy zombie guts surged out of the zombie's tummy and all over Michonne.
