The Walking Dead: Dead Reckoning
Leon appears as Shane's subordinate in this episode. He is first seen picking up an infected man named Robb Spanner at a bar who he thought was drunk. Leon took him back to the King County Sheriff's Department and placed him in a holding cell. Later, after Shane brings in a local civilian named Gary Taylor for domestic disturbance and possibly murder, Leon was bitten in the thumb by Gary and it is debated for a while by Shane whether he is infected or not. After the third police officer at the station, Don, is killed by a now-reanimated Robb who then attacks Gary, Leon helps Shane kill Robb. Shane has a conversation with Gary after beginning to believe that Gary was not a murderer and acted on self-defense. It is revealed that Gary isn't infected; meaning Leon isn't either. There is then a crash at the front desk, in which Leon goes out to investigate. He discovers that Gary's daughter, Patty Taylor, has become a walker due to an injury she received from her zombified boyfriend, Paul. Shane saves Leon and is forced to kill Patty. After this, Shane, Leon and Gary go outside and talk about what they will do about the chaos that's occurring everywhere. Shane decides to go to the hospital to get Rick and then take Rick's family to Atlanta. Leon, on the other hand, decides to stay in King County, where his guns are, and help the people there, like Gary. He and Shane shake hands before the latter departs, heading for the hospital. As Leon and Gary watch him drive away, a now-reanimated Don leaps out of the police station and attacks Leon as the screen abruptly goes black. It is likely implied that this how Leon became a infected and turned into a walker.
