It should be a time for celebration when Rob graduates from college, but instead, he starts acting out and flaking on his responsibilities, including blowing off an interview for a paid internship that his sister Kourtney hooked up for him. His family starts to become concerned when they find out that he stole Kim's prized Bentley and gets two new huge tattoos, including one of his late father. Will they be able to talk some sense into Rob before he ruins all of his opportunities? Also, Khloe feels like she is being treated differently from her sisters and takes a DNA test to see if Kris is her real mother.
