No Exit - S5.E20

An airborne contamination alert locks down the West Wing, forcing staffers to stay put until the all-clear is sounded; Toby and Will face off over Will's working for the vice president; C.J. tells Donna some things she's rather not hear about Josh and her career prospects; Leo confronts Abbey about the dangers of her recent coping mechanisms; Jed, Debbie, and Charlie are poked, prodded, and sent to the decontamination showers; Kate is initially reluctant to give Josh any information on a personal or professional level as they sit out the alert together.
