Glee has already increased the number of people in the freshman class since the first season, but it seems as though the expansion is not yet over.
TVLine has made it known that actress Melissa Benoist, who can be seen on the top left, and quite a newcomer Becca Tobin will be joining the cast of Glee for the 4th season.
Benoist and Tobin will both be McKinley students, with Benoist as Marley and Tobin as Kitty. These characters will also be permanent. This sounds interesting!
