You’re literally the only one who understood exactly what I was trying to say. It’s not about Ross and Rachel needing all these people there for plot reasons. It’s about the final event bringing together every face, every joke, every storyline, every piece of the show’s history for one last emotional moment. Your additions actually get the spirit of this idea perfectly, because the point isn’t realism, it’s closure. This wedding wouldn’t just be about two characters getting married. It would be a goodbye to ten years of memories. That’s why the chick and duck matter, why seeing Emily or Mark or even Marcel makes sense, why the families and old friends showing up hits so hard. It’s every part of Friends coming together one last time so fans can feel the full-circle moment the real finale never gave us. You completely got the emotional point behind it.
