Themistocles was absolutely unprepared for the face that buried itself in his neck. The command to protect meant to protect himself and to stay away from people. As a general rule, when Rowena left Themistocles was to stay away from people unless they were immediate family. So the young woman at his neck was seen as a threat. The dog's body reeled with shock and the need to attack. His entire body tensed, lips pulling back over his teeth, immense teeth flashing as he twisted free of the woman's grasp and moved to violently snap his jaws at her throat, a growl erupting from low in his belly. Themistocles backed away, his stance threatening and then jumped out the truck, running back into the horde of walkers. Just barreling straight past them. Perhaps he was searching for Rowena. Perhaps he couldn't stand the people in that truck even if he'd been around them for  less than twenty four hours. Either way, he was never seen again, a gash a walker created deep on his muzzle slowly infecting him until he turned.
