So why weren't they in the episode? Well, Heather, for one thing, was heavily pregnant when the tribute was filmed so coming back would probably have been both physically and emotionally daunting (not to mention how hard it would have been to hide her baby bump!).
Whatever the real reason, Quinn's absence was keenly felt seeing as she and Finn have an intense history on the show. Honestly, not seeing either Cheerio was a big disappointment. The episode was a way to honor not just Cory's memory, but specifically the role he had on a show that has touched so many people, so it's sad such essential characters didn't say goodbye.
That said, "The Quarterback" was an overall moving tribute that had us sobbing so much we barely noticed who was and wasn't on camera.
What do you think: Were you disappointed Heather Morris and Dianna Agron weren't in the episode, or did it not matter? Sound off in the comments below!
