   Summary

   Agatha and Rio used to be best friends, until one fateful fight tore them apart.

   Ten years later, Rio is living her best life as an out and proud lesbian when the person she never thought she'd see again shows up at her friend's dinner party as a plus-one.

   Agatha Harkness— Tony Stark's girlfriend. Straight.

   (Except only one of those two things is true.)
