Paul Wolfe, known as Operations, is the commander in chief of Section One and he's often looking over Birkoff's shoulder or "breathing down his neck". He's always been ruthless about Birkoff, ready to send him into abeyance at the first mistake, or to replace him with Greg Hillinger if that's convenient. He sends Birkoff in an undercover mission before Birkoff is ready for one.
Birkoff: I can come back.
Madeline: Operations and I were just discussing the
reactive behavior of many of our Operatives. Apparently, you were one of the
only ones on the floor who kept his head.
Operations: As a matter of fact, Mr. Birkoff
exhibited more control than was even necessary... for which I am grateful.
