Hi Emma, I'm Manx! I am going to cheat and respond to all three of your characters here because I am slow to post this. :c
I play Ursula de Luca, a Ribbonfin junior. She is not-so-affectionately called princess around these parts and is a notorious gossip and troublemaker. Ursula is default friendly with most people and she comes from New Money wealth.
DRU. Ursula is also a member of the Event Committee! Otherwise, they're a year apart and in different houses, so not too much regular overlap.
ULYSSES. Ursula is a future Parent with High Expectations and revels in her familial obligations, so these two probably are not seeing eye to eye much. As long as the conversation stays light, they seem like they would be friendly enough.
XAVIER. Fellow Ribbonfins! And Ursula is joining LARP this year though she will be terrible and just want people to call her princess in a non demeaning way. Ursula is something of a champion of the meeker Ribbonfins and also shares Xavier's dislike of quick decision making, but she hides this by barking at other people to figure stuff out. :c She pretty much considers all other Ribbonfins to be among her friends.
