Rosie/Relationships

Alastor
Alastor is affiliated with Rosie, though they have yet to interact in the show. In the Hazbin Hotel comic, The Radio Demon, Alastor greets several girls in the Cannibal Colony and afterward asks them to give Rosie his regards.

On Twitter, Vivziepop stated that Alastor and Rosie's relationship is very similar to Jack and Mary's relationship in Mary Poppins Returns.

According to Faustisse, Alastor considers Rosie (along with Niffty and Husk), to be his only close friends. They think that Alastor and Rosie have known each other for a while.

Franklin
Franklin is Rosie's former business partner. Not much is known about their relationship, but after Franklin is eliminated during The Extermination, Rosie (seemingly delighted) crosses out his name from the sign on their business.
