here's Anne, Holly, Ronnie and Laura :) all minor characters in Hunt.
Anne and Holly are exes of Johan and Jason respectively. They can both be previously seen here (though Holly's design has changed significantly)
Ronnie is Kai's classmate. He's half Japanese, trans and on T. he's also balding.
Laura is one of the people living in the same building as the main gang. She is also trans (i think) and lives with her dog, an irish wolfhound. She has a missing arm.
