Huh!? Something doesn't sound right here!!
According to a source involved with the show, Dianna — who played Cory's girlfriend in the beginning of the series — wasn't welcome to film his tribute episode with the other original cast-members.
"It’s shocking, because even though she’s not contracted for this season, many other actors returned to pay tribute to Cory…even ones with less of a story connection to Finn than Diana had! Remember, she played his GIRLFRIEND on the series, and was a major part of his storyline. [But Lea Michele and Ryan Murphy] intensely dislike Dianna and have both worked to marginalize her as much as possible. They never saw her as a team player. They simply did not want her sharing the glory for this very special episode."
Hold up. Hold up. HOLD. UP!
Didn't she release a beautiful statement when he passed? And hasn't she spoken incredibly fondly of him whenever asked on her Family press tour??
