We've already met Ben (Adam Scott)'s parents on Parks and Recreation - portrayed brilliantly by Glenne Headly and Breaking Bad's Jonathan Banks - but apparently we're not finished meeting his family just yet. According to EW, Annabeth Gish is set to guest star in an upcoming episode as Ben's sister, Stephanie Wyatt. 

Gish, best known for her portrayal as FBI Special Agent Monica Reyes in seasons eight and nine of The X-Files, will appear in an episode that sees Ben and Leslie take a trip up to Ben's hometown of Patridge, Michigan. This is also the city that Ben became mayor of when he was 18, only to subsequently bankrupt the town by trying to open a huge ice rink complex.

The episode is set to begin production next week, and should air sometime later this year.
