Synopsis

A careless mistake by Pam introduced a problem into the office, and she found herself indirectly responsible for Meredith’s discomfort. Dwight, predictably, declared war on the invaders, vowing their complete eradication. Elsewhere, Jim enjoyed a remarkably successful day in Philadelphia, charming a prospective business partner. And in a separate thread, Phyllis, Nellie, and Kevin conspired to interfere in Darryl's romantic affairs.
