when does jim come back on the office
Jim Halpert In "The Merger", Jim's and Pam's reunion is awkward. Pam is overjoyed, but Jim is clearly uncomfortable. He lets Pam know that he is seeing someone, and gradually Karen is introduced as his girlfriend. As Jim settles back in at Scranton, he uses his promotion as an excuse to avoid his old interactions and pranks with Pam, claiming that pulling pranks is not appropriate for his position. However, in time, Jim does return to his old ways, especially targeting Andy Bernard, a Stamford transfer, and Dwight.
The Manager and the Salesman As Michael sets up his desk at the sales section, Dwight (Rainn Wilson) calls a meeting with Ryan (B. J. Novak) to think of ways to take Jim down. Ryan angers Dwight with his tardiness and The Lord of the Rings references. They ultimately try getting Nick, the new IT worker, to give them Jim's computer password, but he refuses. Meanwhile, Michael has a difficult time adjusting back to sales, particularly since he can no longer command Erin's services and is exposed to Phyllis's noxious flatulence, a side effect of her new allergy medication. He confides to Jim that he wants the manager job back and they both tell Jo. While frustrated by their fickleness, she allows them to switch. Michael and Erin celebrate his return to his office, and Dwight taunts Jim about his demotion. In a return to his old ways, Jim dips Dwight's tie in his coffee as Pam grins.
