Jimmy discovers that Gretchen has been sneaking out of the house at night and suspects she's having an affair. Lindsay's life spirals as she discovers she doesn't know how to live on her own. Edgar takes Dorothy out on a date.
Jimmy finds Gretchen's other cell phone and uses it to set up a meeting with the person he thinks she is having an affair with.
Lindsay can't function at home, particularly when the power is cut for non-payment. She calls Paul, who asks what she's been doing with the checks he sends.
Paul starts to offer more help, but he is stopped by Amy, and he instead tells Lindsay she must learn to deal with it.
Edgar asks Jimmy for tips on asking Dorothy on a date. When he does ask her, she tells him about the hazing she has to deal with from the men in the improv troupe. Edgar tells her to take a stand. The troupe breaks up as a result.
Gretchen takes Sam and his wing men to relationship therapy to fix their "fake feud" that has become real, but the therapy is no help.
Jimmy takes Lindsay to lunch, hoping to find out more about Gretchen's activities.
Lindsay tries to walk home alone and gets hopelessly lost. She takes refuge in Vernon's basement man-cave, raiding his stash of "medications".
Jimmy takes Gretchen to the "date" he set up, at a pretentious "artisanal water" bar. Gretchen meets Ty there, finding him repulsive as usual.
Jimmy discovers the "date" is with Sam, who gave Gretchen the phone in the first episode to keep her on a leash.
Lindsay thinks Paul has come to comfort her in the man cave, but she is hallucinating and it is actually Vernon, who fondles her boob before deciding to decline her advances.
Following Gretchen that night, Jimmy finds her alone in her car, crying.
