I can't believe that camera man Brian got fired for stepping in for Pam!!! What else was he supposed to do? That big dude Frank was coming after Pam and he looked like he was going to hit her. So? I think Brian did the right thing. He wasn't going to let some scary, big man hurt a woman! I just don't understand why he was fired. Back when Dwight sprayed Roy in the face with mace, Dwight was seen as a hero. And he was. Roy would have crushed Jim.

So if Dwight wasn't fired for doing the right thing, why was Brian let go?

The twist of acknowledging the documentary crew has, ultimately, made the audience feel no longer welcome.
