Robyn really should be demoted at this point. She should be a friend like Marlo who pops in when they have group outings. We don't need to see her be Gizelle's sychophant in every scene.
The only thing that would help her case is a beef with Gizelle. Which she ain't gon do.
Wendy can fulfill Robyn's role of observant commentator. That's literally her career.
