Why Dianna Agron wasn't in the quaterback episode ? She was an important part of Finn's history in glee.

There was some rumor that's because she was in bad terms with Lea & Ryan Murphy, so wasn't invited (link) but I highly doubt it. She seemed really close friends with Lea...
Other source said it was because of schedule conflicts (link), as she's promoting "The Family" now, with Robert De Niro, Michelle Pfeiffer, and Tommy Lee Jones.
Anyway, it's really a pity she was missing, she was such a big part of Finn's story...

Apparently there were scheduling conflicts so she couldn't be in it :(

I missed Quinn so much in this episode.

Dianna was in another country at the time to promote her movie. I dont know which movie but thats what she was doing. Some people are saying that the cast didnt want her in it because she was kind ofa snot to them but thats not true. Thats just a rumor. Also, I agree. I was hoping she would be in it too. Did anyone notice that heather was gone too? I dont know why. Luckily both Dianna and Heather will be jn the 100th episode of glee in march. Yay!
