|Specifics: This is for Ghostbusters 101|
Patty Tolan is one of the four Ghostbusters in the 2016 movie.
She is the practical, street smarts member of the team. She also is a wealth of information on New York city's history.
She being a MTA worker, meets many "characters" in her line of work, but Rowan North takes the cake. One day she noticed him disappear going down the tunnel. While searching for him, she finds a odd sparking device. Then she sees a ghost. She visits the Ghostbusters and asks for their help.
Patty and Holtzmann went to Queens in search of a ghost to trap for study. After spending a great deal of time there, they encountered Ralph and gave chase. Unaware of a portal that was briefly open in a park, they caught up to the ghost and fired. Patty admonished Holtzmann for blowing up another car. Holtzmann insisted the ghost used its psychic powers to do it. Patty was not too pleased to be drenched in ectoplasm after Holtzmann blew the ghost up. Patty called up Abby and informed them they came up short again. Abby told Patty to inform Holtzmann she couldn't blow up anymore ghosts until they trapped at least a Class 5. Patty also informed her Holtzmann blew up more cars. Abby also placed a moratorium on blowing up cars since they were being threatened with the costs.
