It was such a relief when Pam finally cut things off with Roy and started dating Jim. They found out they were expecting a baby, got married, and proceeded to have their happily ever after scenario … at first. Things got pretty thorny when it was revealed that Pam had become super close to Brian, the sound operator for the pseudo-documentary.
In fact, Pam and Brian had gotten so close that he was the one who comforted her when she started crying after an emotional conversation with Jim over the phone.
When Jim found out how close Pam and Brian were, it made him feel uncomfortable — understandably. Even though Pam was emotionally drawn to Brian and his ability to support her through her negative feelings, she didn’t actually cheat on Jim with the guy.
Once she realized she should have saved her emotions for intimate conversations with Jim instead of Brian, her marriage with Jim started to heal. At the end of the day, neither Jim nor Pam cheated on each other throughout the course of the show.
