As Peter Venkman, Ray Stantz, and Egon Spengler walked downstairs to their laboratory, after their investigation of the New York City Public Library, they discussed who should be getting Nobel Prize for their research. As they reached their door, Jan was bent over getting some tools ready. After Peter mused he deserved some credit, he greeted Jan as the three scientists entered the lab. As soon as the door closed, Jan began scraping their names off the door with a razor blade.
- While the Stairwell scene existed in the 8/5/83 and 10/7/83 drafts, the Jan character was simply referred to as 'Workman' in them.
