Initially, Bub had the typical mentality of any other rabid zombie; however thanks to Logan’s training and reeducation, Bub has regained some human intelligence. Logan concluded that Bub was able to unlock his memories from before his death and transformation into a zombie, as seen when Bub recalled how to use a razor to shave his face despite Logan never showing razors to Bub before. His intelligence continued to develop; Bub was able to speak a mumbled sentence, and his intellect even allowed him to operate and use a pistol. Later he would escape his chains by loosening an exposed screw, and accurately concluded that Rhodes was responsible for Logan’s murder.
When Bub speaks saying “Hello Aunt Alicia.” Rhodes drops the clip board in shock, gaining Bub’s attention. Bub, apparently recognizing Rhodes as a soldier, offers a salute to Rhodes, causing Steel to laugh. This prompts Logan to believe that Bub was in the military in life. Logan asks Rhodes to return the Salute, which he refuses, seeming to anger Bub. As part of a demonstration, Logan asks Sarah to empty her pistol and hand it to Logan. As a show of respect, Logan then salutes Bub before placing the pistol on the table. Bub looks at the pistol and cocks it, aiming at Rhodes, prompting Rhodes to pull his own loaded gun on him. Bub tries to fire his gun, only to hear the pistol click, reacting in fear that the gun is empty. He puts the gun back down, but Rhodes refuses to lower his own, intending to kill Bub. Logan stands between them, protecting Bub.
While Bub plays with the razor and tooth brush he throws them away after a while. When he starts reading the book, Logan congratulates him enthusiastically. Ted argues how pointless it is, due to him witnessing the dead do similar things such as trying to drive a car. However Sarah argues, that it’s more on the fact that he didn’t attack or try to eat Logan during the demonstration. Rhodes and his Private, Walter Steel; interrupts their conversation at first acting hostile towards Bub, but Logan insists that Bub is docile. He invites them all in the room and hands Bub the phone in an attempt to get him to speak. Steel think’s its ridiculous and Rhode’s just examines the clipboard.
Bub stalked Rhodes through the complex, shooting him several times, until Rhodes bumped into a horde of zombies.
Bub was apparently in one branch of the United States Military before the Zombie outbreak, possibly the US Army or Marine Infantry seeing as he recognizes ranks and can handle firearms with ease. When the undead apocalypse occurred, Bub died and reanimated. He was one of the zombie specimens captured by the Seminole Storage Facility from the zombie-infested caves.
They discover much to their horror, that Bub’s reward for being docile is being fed human flesh as positive reinforcement. Matters get worse when Rhodes walks in an discovers the travesty. They discover the source of the flesh is the remains of soldiers that have been killed, prompting Rhodes to shoot Logan killing him. Bub is later seen locked up with another Ghoul and he figures out how to get the chain off his leash, freeing him. While that is going on Miguel in a frenzy has lead a horde of the dead into the facility prompting everyone to scatter. When Bub goes to show what he learned, he discovers Logan’s corpse in the freezer. When he realizes Logan is dead, he becomes grieving and enraged.
Bub is later seen with Logan playing with a set of headphones he has on his head. When Logan tries to adjust the headphones for him, Bub instinctively grabs his arm before letting him go, showing his trust in Logan. Logan adjusts his headphones, while teaching him how to play the tape recorder. The music being played was “Ode To Joy.” By Beethoven, music Bub seemed to enjoy. When Logan shut it off, Bub was at first saddened, but per Logan’s teachings, learned how to play the tape himself so he can listen to it whenever he wanted. After Logan makes his note, he turns off the recorder to tell him, that it’s time for his reward. Unbeknownst to both of them, this particular demonstration is observed by Sarah and William “Bill” McDermott, who came to the lab to get morphine for the bit Private Miguel Salazar.
Bub (real name unknown) is a Zombie who was “domesticated” by Dr. Logan.
Eventually, Logan rewards Bub by feeding him the fresh remains of Miller and Johnson. Later, Bub is able to figure out how to remove his chain, and discovered Logan dead in the freezer where he eagerly tried to show the slain man that he removed the chain only to realize he has been killed. Enraged at his mentor’s death, Bub acquired a discarded gun and went on a hunt for Rhodes in the complex, attacking Steel before meeting his final objective.
