Janine is the OGB's plucky former secretary. She's spent the last decade flitting from job to job... trying not to pine for Prof. Spengler. (It's not that Egon doesn't like Janine... it's just that romance is so unscientific...) When the Ghostbusters re-formed, Janine found herself heeding the call.
She's the bookkeeper, the office manager, the mother hen, and more. Janine's soaked up enough knowledge to be an EGB herself, and there are times when the constraints of her (largely) office-bound responsibilities will frustrate her; she's not afraid to get her hands dirty when the situation dictates.
