So post-movie there is some mutual interest between Andy and Nile - maybe they start a relationship or not, but then Quynh comes back! After the emotional fallout and drama, Andy and Quynh are very much happy to be back together. Nile also feels happy for them but also a little disappointed because of course, how could she compare to the love of Andy's life who she was with for thousands of years? Lots of misunderstandings ensue as Andy and Quynh invite Nile to their bed but she assumes its just a casual thing. At some point this is realized and Andy and Quynh make it clear that despite only knowing Nile for a short time, they both have strong feelings for her and are very much interested in a full-fledged relationship if that is what she wants. Would especially love to see Nile and Quynh interaction!
Ideally, ends with Andy and Quynh taking it upon themselves to show Nile just how much they love her, and lucky Nile being the subject of both their attentions.
Andy/Nile to Andy/Quynh/Nile
