Hide and Seek is the sixth episode of the first season of Severance.

We serve Kier, you child!

Mrs. Selvig, dressed in a matronly white nightie and braids, sits on an institutional-looking bed in what appears to be her basement. She makes a necklace out of a severance implant and admires it in the mirror. Her phone buzzes. It's Graner. Tests on Kilmer's chip show the console used to hack the chip has a signature that ties it back to Lumon. Graner thinks it traces back to Reghabi. He's going to look for her. Selvig ends the call.

Selvig kneels at an altar illuminated by white candles and folds her hands. A framed black-and-white photograph of Kier Eagan hangs centered above it. It is surrounded by numerous articles of Kier-adjacent totems and memorabilia - an original canister of Lumon Industries topical salve, a yellowed snapshot of a girl in braids standing next to the sign for the Myrtle Eagan School for Girls, and, strangely, a coiled ventilator hose labeled Charlotte Cobel, DOB 3-17-44. She begins to recite, or pray: “Tame in me the tempers four / that I may serve thee evermore. / Place in me the values nine, / that I may feel they touch divine.”

Mark hurries down his basement steps and digs Petey's phone out of the box. He checks it, closes it and pockets it. He gets into his car, turns on the engine, and pulls out of his driveway. He backs up on the road to get even with the trash bins. He rolls down his car window and removes the battery from the phone. He throws both pieces in the trash.

Lumon, Severed floor. Irving and Burt enter a room filled with greenery. Burt tells Irving he found the place a while ago and sometimes visits it by himself. Irving thinks it's beautiful. Burt suggests it can be their secret place. They quietly discuss the Lumon rules on workplace romance. Burt goes in for a kiss. Irving can't do it; he isn't ready. He apologizes. Their foreheads meet in a kind of embrace. Burt asks Irving to stay there with him.

Devon strolls through a snowy park with Eleanor strapped to her front in a carrier. Below her, in an open area, Devon spies Gabby. She waves her hand and calls out a greeting to her. Gabby doesn't recognize Devon. Devon walks down to get closer. She re-introduces herself, mentioning the coffee. Devon asks how William is. Gabby answers, a little put off, “His name's Bradley, actually.” Gabby's husband wanders over and introduces himself - Angelo Arteta. He asks if Devon and Gabby know each other. Devon mentions meeting at the birthing cottages. Angelo quickly rounds up his wife and two boys, and they leave the park, leaving Devon bewildered.

Mark reads The You You Are secretly in the storage closet, totally absorbed in Ricken's not-entirely-accurate prose.

Assembled in the kitchenette, Dylan, Helly and Mark listen to Irving as he tries to convince them all to go back with him to O&D. Dylan suspects Irving just wants to see Burt again; Irving insists it could be the start of uniting the two departments. Mark asks Irving to clarify what he meant by O&D making things. Irving responds that they didn't ask. Dylan suggests O&D are making goat-murdering implements. Helly believes O&D is an important piece of the puzzle. Then Mark and Helly have a flirty moment, leaving Mark looking a little flushed.

Milchick walks in on Irving and Dylan ribbing Mark and asks what they're talking about. Together, trying to recover, they come up with “Ms. Casey.” Mark, suddenly realizing he hasn't seen her, asks where Ms. Casey is.

Mark is in Ms. Cobel's office. She sternly lectures Mark about accountability. Mark tries to defend Ms. Casey, reminding Cobel that he is the one who snuck Helly out of MDR, and he should be bearing the consequences for what happened, though he covers their excursion as “just a walk.” Cobel zeroes in and shows him security camera footage of Mark and Helly in the unused office. Cobel reprimands Mark for exploring the halls while MDR has still not met its quarterly quota. Mark demands to know what their actual job is for. “We serve Kier, you child!” Cobel screeches at him from across the desk. She revokes MDR's hallway privileges.

Dylan sulks that Ms. Casey hasn't returned to MDR, saying he wore a nice shirt just for her. Helly retorts that his Outie doesn't know anything about Ms. Casey; Dylan proposes that love transcends Severance. He tries to turn the conversation to Helly and Mark, insinuating that “baby goats” is a euphemism for a tryst. Helly attempts, possibly unsuccessfully, to convince Dylan that there were actual baby goats.

Mark gets back to MDR from Cobel's. He tells Helly and Dylan that Ms. Casey is in the Break Room. Mark angrily tells them that until they meet their quota there are no more inter-departmental visits. Irving apologizes to Mark for the bad example he has set. Mark asks Irving to take them all to O&D.

The four walk the hallways defiantly. Cobel sees it on her camera feed and shouts for Milchick. “I'm on it,” he says.

Burt takes the four to the back room of O&D. Helly and Mark are astonished by the number of people working there. Burt tries to ease the surprise to his workers. He welcomes MDR and hopes O&D would be welcome in their office as well. Burt encourages the O&D people to ask MDR a question. One woman, holding a white watering can, asks what MDR refines. Mark struggles to find an answer. Irving asks if she has a watering can. She looks at Burt searchingly; he guesses they are supplies for the executives upstairs, though the hatchets they made last week had more of an aggressive feel.

Mark tells everyone that they have been trying to figure out how it all fits together. He mentions the baby goat room. Burt stresses that everything they do there is important. Helly questions his statement.

Mark proposes working together to try to find out more. He points out that nobody will tell them what they're doing; that they work in the dark while the Eagan philosophy is “Illumination beyond all.”

Burt agrees with Mark's argument, adding that he and Mark should go to the goat department together and find out what they know. While Burt makes this case, Dylan strolls the room. Dylan finds a bin with picture cards in it. They illustrate movements and attack stances. He takes one and pockets it.

Milchick opens the back-room door and looks upon the scene with disappointment and accusation. He walks MDR back to their office while Mark protests. Cobel is waiting there for them. She sings a short song in tribute to Kier. After she finishes, she dresses Mark down for the breach of trust. Graner appears. Cobel tells him to take Mark to the Break Room.

As Mark enters the hallway to the Break Room, the door at the other end and Ms. Casey comes out. They walk toward one another. Mark whispers, “I'm sorry” as they pass each other in the middle.
