Bill tells Budd that Beatrix killed all of the Crazy 88's and O-Ren Ishii while using a Hattori Hanzo sword. Bill asks him if he has continued training and Budd tells him he pawned his Hanzo sword years ago. He tells Bill he now works as a bouncer in a strip club and if Beatrix wants a fight, she just has to go to the club and start one. Bill offers to help Budd, but Budd tells him he deserves what he has coming to him. Budd arrives at work and Jay tells him he is late again, while Lucky sits nearby and Larry Gomez yells at Budd to get into his office. Larry starts chewing out Budd and Trixie asks him if he wants her to leave. Budd tells Larry there isn't anyone at the club yet and Larry gets upset and starts removing days Budd is supposed to work. Larry tells him to go home and wait for him to call him after he does a job for Rocket. Rocket walks up to Budd and tells him the toilet is overflowing and he needs to unclog it. After work, he drives home and notices something is up. He goes inside of his trailer and turns on his radio. Beatrix slinks out from under his trailer with her Hanzo sword. She opens his door and is shot by Budd with rock salt shells in the chest. He injects her with a tranquilizer and she falls unconscious. He calls Elle Driver and offers to sell her Beatrix's Hanzo sword for a million dollars and she agrees. Beatrix wakes up to Ernie digging out the remains of Paula Schultz who died in 1898. Ernie finishes and Budd pulls him out of the grave and as they grab Beatrix she struggles. Budd threatens to shoot her directly in the eyes with mace unless she calms down and she complies. She is put in a coffin and the lid is nailed shut after Budd tells her it is for breaking Bill's heart. The coffin is put into the grave and then Budd and Ernie fill the dirt back in.
Elle drives to Budd's trailer with a suitcase full of money as Beatrix makes her way in the same direction. Budd tells Elle what he did to Beatrix and he offers her a drink. He tells her what grave she was buried in and Elle looks at the Hanzo sword. She asks him how Beatrix's sword compares to the one Budd had and he tells her no Hanzo sword can be compared to another. He asks her if she is filled with relief or regret knowing Beatrix is dead. She tells him she feels regret and Budd opens the suitcase full of money. As he is pulling out the stacks of money, he is suddenly struck by a black mamba multiple times. Elle pulls out a notepad and tells him the fatality stats of the black mamba. Before he dies, Elle tells Budd the biggest regret she feels is that he killed Beatrix and not someone else better skilled.
