‘Glee’ season 4 spoilers: Heather Morris, Blake Jenner on filming ‘Grease’

What is coming up on “Glee” moving forward? Let’s just say that there will be plenty of dancing, some returning faces, and also some “Grease.” With all of this in mind, we have a new video featuring such actors as Heather Morris and Becca Tobin talking about something that is very big when it comes to what is coming up … including the return of fan favorites Harry Shum Jr. (Mike Chang) as well as Amber Riley (Mercedes).

The bad news here? This new video (which is coming to us via TVLine) does not really do much when it comes to actually giving any scoop about the storyline coming up. However, Jacob Artist (Jake) confirmed that the scene they are working on is from the callbacks to the upcoming “Grease” musical, and this is one of the first opportunities that he has had to show off some of his dance moves on the show. The person with the most impressive moves here, though, are Tobin along with “Glee Project” champ Blake Jenner (who makes his debut during the episode), as they both take part in a double-cartwheel move that is really cool to watch considering how tall he is and how short she is.

The one major question that we have in watching this is simply the following: why in the world would Tobin’s Kitty ever want to be a part of such a musical? She seems to be the sort of character who is really all about cheerleading and doing what she feels is “cool,” and thus far that has not included joining forces with New Directions. The only explanation we can think of is that she is trying to use this as some sort of means to hook back up with Jake or maybe even Jenner’s Brody, since everyone knows rehearsals take up plenty of time. (Of course, all of this is in violation of the key role to not fall in love with the people you spend time with on stage; why isn’t that ever mentioned?)

What do you think about this video, and which one of the returning actors are you the most excited to see?
