Complete story — includes the ending
Kimmy throws a party for her 30th birthday, but is unpleasantly surprised when her incompetent state trooper step-father Randy ( Tim Blake Nelson ) and half-sister Kymmi ( Kiernan Shipka ) show up uninvited. At the party, Kymmi lashes out at Kimmy after Randy gives her a locket that belongs to Kimmy and Kymmi's absentee mother. Meanwhile, Logan and Dong compete for Kimmy's attention at the party, culminating in a fight and Titus invites an attractive coworker to the party without seeing his face, only to realize that the coworker is someone he has previously dated. At the height of the chaos, Kimmy kicks everyone out for ruining her birthday, and discovers that Kymmi has run away. Kimmy tracks her down to an Olive Garden in Times Square and manages to reconcile with her sister, commiserating with her on how hard it is when you don't get a childhood.
