She receives a call from her boss

Lauren's boss (Miss Hedgeworth) is the only person who knew about Lauren's little secret. she found it infuriating to watch a dumb younger woman, strut around like she owned the place. So she came up with a plan to put that bratty 20 year old in her place.

Lauren enters the room in her normal, overconfident manner, and asks why she was called in.

Her boss tells her about an undercover mission she has to do.
