In 1887, during a terrible storm, Simon Quegg's cruelty manifested in his horse, buggy, and a third entity called the Dark Rider. The horse and buggy were essentially bonded to Quegg and if separated, would be attracted to him like a magnet. When Ray Stantz shot at them, he switched places with Quegg. Egon later theorized if he, Winston Zeddemore and Peter Venkman shot three streams simultaneously at the horse and buggy, they could free Ray. 
However, a lightning strike overloaded the Proton Packs and the theory was never confirmed. Instead, Quegg was convinced to confront the Rider with Ray. When Quegg discovered he was the Rider, he shoved Ray off the buggy. After the Rider was dispersed, Quegg thanked the Ghostbusters and happily rode home in the horse and buggy.
