I'd love to see Newt and Tina as a committed couple who realize that they want to be in a committed triad - with Graves. How do they woo him? Do they start with a threesome as a fling? Etc. Percival as a bisexual equally attracted to both Tina and Newt, please.

+ For relatively inexperienced Graves
+ For this kind of arrangement being unusual in the wizarding world
+ For one watching while two have sex and being super turned on (maybe this is how Newt and Tina get Graves involved?)
