I only get Maddie, Star, Paulina, and Kate as options for donors. I am on a Sam as date to the dance path. Thoughts?Yes. During Ember's questline (ep. 7), Sam will offer herself as an Orgone 'donor' and Danny will need to pick a second 'donor'. If you choose Desiree, you'll get an h-scene* after the party and lizard fight. It'll be different from the one you get after the dance.
*the build-up to the scene is quite touching. It's one of the best moments in this game
I did do all the date paths at the time but chose Sam as my path to continue so I have seen all the after dance scenes.
Along those lines, on a Star orgone donor choice from my Sam path, Star talks like Invisi-Bill took her to the dance in a bitch fest with Paulina.
