Sheila Miller

Sheila Miller (age: 40s) is a food service assistant at the CIA North Dakota Black Site cafeteria.

Friendship with Edith Whitmore
Sheila attends the Devils Lake Methodist Church, where Edith Whitmore serves as pastor. The two share a love of baking and often exchange recipes of baked goods. When Edith Whitmore goes missing after attempting to convert the Maudlings to Christianity, Sheila is devastated and promises Harold Whitmore that she will do anything she can to help find Edith.

Friendship with Johnny Cameron
Starting in season 3, Sheila begins making small talk with CIA Agent Johnny Cameron. When she discovers that salted caramel cookies, the type of cookie that sells out the fastest, are his favorite cookie, she begins to save one for him when she is able to. It is unclear if Sheila has romantic feelings for Johnny or if she views him more as a child who needs protecting. In season 4, after telling Johnny that she wasn't able to save a cookie for him today (much to Johnny's disappointment), she finds a spare salted caramel cookie in the kitchen and brings it out to his table. As she's approaching the table, she overhears him telling CIA lab tech Alan Crenshaw that the CIA has arranged a meeting with the Maudlings in the scrapyard the following week. Sheila later brings this information to Harold Whitmore, explaining that it might be a good opportunity to learn more information about his wife's disappearance.
