Robby was found harassing Alice shortly after Nicholas Finch's arrival in Buckaroo.
Robby later attempted to murder Morty at the morgue when he was announcing his findings of the burnt body. When he attacked Finch and Crane at the Serial Killer Graveyard, he admitted to helping Hank burn down the hotel to cover up evidence. He told them it was to stop the legacy of the town killings. He committed suicide after being questioned who put him up to the activities.
