Even minute details, such as how Pam wore her hair each day, were considered by executive producer, Greg Daniels.

"So, I gave very short one-word answers and I tried very hard not to be funny or clever, because I thought that the comedy would come out of just, you know, the real human reactions to the situation... and they liked that take on it.

[10] Originally meek and passive, the character grew more assertive as the seasons passed, prompting Fischer to reassess her portrayal.

In "Gay Witch Hunt", the season's opener, it is revealed that Pam got cold feet before her wedding and did not marry Roy after all.

Meanwhile, Jim has transferred to a different Dunder Mifflin branch, in Stamford, shortly after Pam rejected him a second time after their kiss.

Pam moves into her own apartment, begins taking art classes, a pursuit that Roy had previously dismissed as a waste of time, and buys a new car.

After attending an after-work get-together at a local bar with their co-workers, Pam, feeling that she should be more honest with Roy, tells him about Jim kissing her at the casino night.

Affected by their statements, Pam tells the documentary crew that she is going to be more honest, culminating in a dramatic coal walk during the next-to-last episode of the season, "Beach Games", and a seemingly sincere speech to Jim in front of the entire office about their relationship.

Jim withdraws his name from consideration and drives back to the office, where he interrupts a talking head Pam is doing for the documentary crew by asking her out for dinner.

She happily accepts, visibly moved, abandoning a train of thought about how she would be fine if Jim got the job and never came back to Scranton.

Although Jim is supportive and tells her he will wait for her, Pam ultimately makes the decision to return home, realizing she hates graphic design and misses Scranton.

When CFO David Wallace makes an offer to buy the company, Michael negotiates in order to get their jobs at Dunder Mifflin back instead, including adding Pam to the sales team.

In "Counseling", Pam feels inadequate about her poor performance in sales and tricks Gabe into promoting her to a phony new salaried position called office administrator.

She begins her maternity leave after "Gettysburg", and eventually returns when she and Jim bring Cece and Phillip into the office.

Early in season 9, Jim is restless about his life in Scranton and helps a friend start a Sports Marketing business, Athlead, in Philadelphia.

Jim begins spending part of each work week in Philadelphia; in "Customer Loyalty", the strain of this on Pam is evident when she breaks down in tears.

In "Moving On", Pam interviews for a job in Philadelphia to be closer to Jim, but she is turned off by the idea when her prospective new boss bears a striking resemblance in behavior to Michael Scott.

From her years working the front desk, Pam has become well-acquainted with the Dunder-Mifflin staff and is consistently shown to have a thorough understanding of her coworkers' personalities, including the more eccentric individuals Dwight Schrute and Michael Scott.

She uses this familiarity to manipulate them, often for their and the company's best interests (such as her giving the staff elaborate instructions on how to handle a heartbroken Michael in "The Chump") but also occasionally for her own.

This familiarity plays a large part in her efficiency as office administrator and was crucial to her being promoted to the previously non-existent position.

The "will they or won't they" tension between Jim and Pam is a strong story line in the early episodes of The Office, encompassing much of Seasons 1 to 3.

In Season 2, when Jim encourages Pam to pursue a graphic arts internship offered by Dunder Mifflin, Roy objects to the opportunity and eventually convinces her that the idea is foolish.

He often makes suggestive, yet harmless remarks about her beauty and general appearance, and at one point lies to the camera that they used to date.

As Michael takes off his microphone and heads down the airport concourse, Pam runs to him with no shoes and hugs him as he kisses her cheek.

In "A Benihana Christmas" she gives him her Dunder Mifflin bathrobe, a display of friendly affection, after he spent the day feeling bad that Dwight took his.

In "Dunder Mifflin Infinity", Toby witnesses Pam kissing Jim Halpert in the break room, which prompts him to issue a memo about public displays of affection in the workplace.

In his mortification, Toby immediately announces that he is moving to Costa Rica before jumping over the locked gate and fleeing.

When Pam learns that someone had complained about her to Toby, she immediately assumes that it was Angela and prepares to uninvite her from the wedding, only to be stopped when Jim admits that he had registered (and subsequently retracted) the complaint.

Angela reveals that the cord for the karaoke machine, which had previously been missing, was hidden in the potted plant right outside the conference room, heavily implying that she stole it to sabotage their party.

However, Pam and Angela later bond when Oscar compares being a parent to owning a dog in “After Hours.” Despite the hostility between the two, they sometimes see each other as friends and talk over the file cabinet between their desks.
