Sylla is her roommate! And actually their backgrounds are pretty similar, come to think of it - Sylla's from a notorious family with nefarious connections back in England, she too has loads of sisters that most are venturing into the dark arts (family business and upbringing, after all), more conservative about the more modern aspects of socializing, both very into duelling? I can see Sylla actually getting along well with her if she was allowed by Clementine? Maybe the Decourts had business deals with the Borgins? IDK I SEE POSSIBLE POTENTIAL? But then the similarities could have Clementine hating Sylla but lemme know what you think?

And Holden mostly stays in his lane and is intimidated af by her, but he's a wimp.
