Rosie/Relationships

Alastor
Alastor and Rosie are good friends. 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.

Alastor describes her as a "dear, charming and dangerous" person who he loves to spend time with. It is apparent that the two get along very well, as they are subsequently seen together, and both enjoy each other's presence. It is also seen that they share several ideas together, and both are always willing to help the other. Alastor allows Rosie to touch him despite usually hating it. Rosie is aware of and doesn't mind that Alastor is asexual, despite the Radio Demon being somewhat unaware of his true sexuality. Their friendship is further highlighted in “Hello Rosie!“, where Rosie was overjoyed to see Alastor again after his long sabbatical and stated that she missed him greatly. As shown, Rosie trusts Alastor fully and assists him when he asks her for help, woth her stating that he never steared her wrong before. Rosie herself is close enough to Alastor to even assist him in acquring more power and influence over Pentagram City, having casually and happilly shared information she acquired about the weak leadership to a section of the city that he could take over with the right deal.

Later, while initially skeptical about Charlie Morningstar when Alastor brought her to her to get the assistance of the Cannibals to fight the Exorcists, Rosie never the less agreed to assist them based on Alastor’s word. Later, Rosie would be delighted to see Charlie’s successs in winning the cannibals over and agreed with Alastor’s assessment of her potential and that siding with her would be mutually beneficial for them.

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.

Charlie Morningstar
Rosie took an instant liking to Charlie upon meeting her, offering her some of her snacks and sided with her plans to get the cannibals of her town to fight against the Exterminators. She also realizes there's more to her stress than the angels, that being her relationship with Vaggie and how recent events have revealed her as a former Exterminator herself. It is then that Rosie sits Charlie down and gives her advice, saying that while what Vaggie in the past was wrong, she never brought it up out of fear of what she would think of her and that it's thanks to Charlie herself that she wants to do better. In the ends, this helps the to two fix their relationship.

Cannibals
Rosie is the leader of the Cannibals of Cannibal Town and they trust her explicitly as their leader. As shown where Rosie helps many of them who go to her Emporium for advice and assistance with dealing their problems, with her even offering to personally assist them in solving them. Rosie’s herself understands the mentality of the Cannibals well and knows exactly how to get them to cooperate.

Susan
As shown in “Hello Rosie!”, Susan is a denizen of the Cannibal Town and is disliked by her and Alastor, with both of them describing her as a “ornary, old bitch”. Rosie herself knows Susan’s unpleasant personality well and that she would be the hardest of the Cannibals to convince when she was coaching Charlie on how to rally the cannibals to help her defend her Hotel from the Exorcists.

Despite her dislike for her,Susan in return seems to like Rosie, at least in comparison to Charlie. As shown when she began booing Charlie during her initial speech and demanded that Rosie come back on stage instead.
