Shelley Mitchell is an office worker from Episode 2.2.
She had to give a presentation to Mr Nagata of Nagata Beer. Her boss Terry greets her at the start of the episode, explaining that her job could be on the line if something goes wrong. An anomaly appears on the top floor of their office building, and a thick fog triggers the fire alarm, but Terry tells Shelley and Mike to ignore the alarm and carry on with their presentation. Eventually, Shelley admits she can smell something, so they destract Mr Nagata with some videos whilst Terry investigates. Shelley then watches Terry die through the glass wall of her office, killed by a Fog Worm. Soon after she smacks a worm with her laptop before Nick Cutter and the ARC team rescue her and Mike. She argues with Jenny Lewis about what happened, but Jenny just sends her away.
