what episode does roy try to fight jim
The Negotiation Roy Anderson (David Denman) enters the office and attacks Jim Halpert (John Krasinski) for kissing Pam Beesly (Jenna Fischer), his former fiancÃ©, but Dwight Schrute (Rainn Wilson) subdues him with pepper spray. Toby Flenderson (Paul Lieberstein) and Michael Scott (Steve Carell) fire Roy, and Jim, feeling guilty about all of his pranks over the years, tries to show his appreciation to Dwight for saving him, but each gesture is coolly rejected, as Dwight believes he only acted in the line of duty and is undeserving of any special praise.
Chair Model While flirting, Jim Halpert (John Krasinski) reveals he is ready to propose to Pam, even going as far as telling her that he is not going to do it at work ("because that would be rather lame") and when he does it, it will "kick her ass". Pam is not sure if he's joking. Alone with the camera, Jim reveals that he was not joking and shows an engagement ring that he bought "the week after [they] started dating." After work, while walking back to his car, he stops and gets down on one knee. When Pam stops and looks he says he has a question to ask her. After a second or so of hesitation, he asks her if she will wait while he ties his shoes. She laughs and they continue walking hand in hand. At the end of the episode, Michael and Dwight are seen singing "American Pie" and dancing in the same cemetery at night, presumably having never left.
