That evening Natalie is on the news dodging questions about a woman who became pregnant unbeknownst to her only a month after her company went severed.
New group photos are received. When Mark is swapping the photos out, he finds Petey's map of the Severed floor on the back of one photo and hides it. Helly is determined to get a message to her outie self, and tries increasingly desperate means, which Mark warns her of the consequences.
Irving suggests the department take a trip to the Perpetuity Wing to help instill Helly with some purpose. on the way they encounter Burt and Felicia from O&D, coming from the Team-building Space having completed an Egg Drop Challenge.
