Jack and Janet are shocked as evidence mounts that Chrissy seems compelled to steal, not only from them but also from the Ropers.
- Janet is miffed upon discovering that her gold pen, a graduation present from her folks, is missing. Then, while Jack is perched on a ladder helping Roper paint the apartment exterior, he peers in his own bedroom window as Chrissy is taking his money from a drawer. Unaware that Chrissy is really borrowing cash for Mrs. Roper's C.O.D. delivery, Jack shares his bad news with Janet. While they are worrying that their roommate has developed kleptomania she walks in with a new purse and Mrs. Roper's shawl.
