You'll find out Sarah has a nasty side. In an upcoming episode, Mason's going to get a job with another senator, where he proposes a parental-responsibility amendment.

Next week, a love triangle starts forming between Pete, Sarah and Lewis. It turns out Sarah and Pete had a fling in high school. Also, Pete and Mason go for the same job at the State Department, rattling their friendship, and Finley gets her dream job at the Smithsonian Institute.
