Canon
Charlie and Vaggie are in a relationship and they also work together in the same work project. Since the beginning, Vaggie is shown to be extremely supportive of Charlie's project of creating the hotel to redeem demons, the Happy Hotel. When Charlie goes to Katie Killjoy's news show to promote the Happy Hotel, Vaggie and Charlie share some intimate moments in the dressing room where Charlie is getting ready, Vaggie asks Charlie if she remembers what she'll say and Charlie excitedly tells her that she does. Vaggie's protectiveness of Charlie is quickly showcased when she grabs her girlfriend by the shoulders and tells her that she can mouth the speech for her if she starts feeling unsure, because she deeply worries about her and wants her to do an amazing job. Charlie reassures her that she's sure of what to say, although she mentions that she just wants to make things more exciting. So in excitement, she gets really close to Vaggie and asks "what if I-" Vaggie completes her sentence asking if she plans to sing a song about it. And this makes Charlie boop her nose in a cute way, saying "you know I was gonna say that", to which Vaggie replies that it's because she knows her. Which shows how well they know each other, their desires, fears and most intimate things about their personalities.

Charlie excitedly gets on top of the table and says she's better at expressing herself through songs. But Vaggie, still worried for her and wanting for her to succeed, tells her " but life isn't a musical, hun." Charlie insists, showing her a plan she made on a paper, but Vaggie just keeps firm on her stance, protective of Charlie. Charlie reluctantly agrees and goes to the studio to prepare for her live appearance on the TV show. Charlie happily extends her hand for the show host to take, but she refuses saying she doesn't "touch the gays". So as soon as Charlie begins to talk, Vaggie is there watching her behind the scenes, supporting her all the way. She even punches a camera person as soon as they insult Charlie.

Vaggie continues to be supportive of Charlie when everything goes terribly bad with her promotion of the Happy Hotel. Later, they get on a limousine with Angel Dust and Vaggie keeps yelling at him for getting out of control and making Charlie look bad as a result. Charlie, knowing Vaggie so well and being perfect at calming her often powerful outbursts, puts a loving hand on her shoulder and tells her that everything will be alright, so it's best to relax. Later, when Charlie sees Alastor come by the hotel, she gets horrified and quickly asks Vaggie what to do. Despite the fact Vaggie tells her not to let him in, Charlie curiously opens the door to him and as soon as he steps in, Vaggie gets defensive of Charlie and her life project, telling him that she won't let him harm anyone or anything in the hotel. Charlie quickly gets behind Vaggie, as she protectively stands in front of Alastor with a weapon.

However, since Vaggie is so supportive and caring of Charlie, she can't help but be suspicious of Alastor and his true intentions in approaching the Happy Hotel, so she tells Charlie that she should be careful when making deals with him. Charlie assures her girlfriend that she's fine and that she can take care of herself, which does little to calm Vaggie, but Charlie's touch is enough to soften her worrisome expression. Finally, Vaggie decides to support her girlfriend, and despite how much she distrusts Alastor, when Charlie smiles at her, excited for her project, Vaggie smiles back at her.
