Please accept Ford for Abraham Ford. Also, I typed "shower," "showers," and "shower room" but not "the shower." Please accept more answers for that as well. As I recall, the katana is only ever referred to as a sword--regardless of the specific kind of sword it is, it is still a sword and you should accept that answer.
You should accept Abraham as the answer for Abraham Ford. Also, the governor is not killed by Machine. He is fatally wounded by Machine and her sword but before he dies or changes he is shot in the head by Lily Chambers. Finally, Machine's sword is never rendered to as a Katana but she is referred to as a Samurai by Woodbury and in the finale by Gareth of Terminus.
Very fun! But you should except Abraham and Brian. It is spelled Lizzie not Lizzy. Also, Lily Chambler is the person who finally killed the governor, Michonne stabbed him, then Lily shot him.
Accept Abraham for Abraham ford and accept Lizzie for Lizzy. Also, Michonne did not kill the governor. Michonne stabbed him, but he was still alive until Lilly shot him.
