Hi Ren! I'm Becca and this is Stella Fawcett. I've also got another character here, just picked her up, named Amelia Higgs.
Stella... well, Stella is going to just love Orsino. She's very, very musical and very, very interested in cute boys with floppy hair. She's a sixth year Ravenclaw but they're in Choir together and her brother, Cal, is Orsino's roommate.
Amelia is a 5th year Slytherin, so they might know each other from the common room. She probably knows he sneaks out for jam sessions but tucks that away for future use. She's annoyingly perceptive that way.
