Congratulations to you, Grey Delisle!
She has become one of my all-time favorite voice actors and I am very happy for her. I didant even know she was expecting. The Fosters cast and crew all seem very tight-nit and family-like so I'm sure that she will get more then she needs when it comes to support. I'm sure that if it was necisary, production on Foster's could be slowed down for her.
That is the beuty of voice acting-the sceduals are usually made around the actor and not the schedual. That dosent mean that they'll put the show on hiatus, but I'm sure that they'll give her some breathing room.
I am really excited to see how Grey's newfound motherhood will show in Frankie. I'm sure that the sence of careing and kindness that we get from her (and made us all love her character) will feel even more real and genuin. Not that it felt fake or anything, ofcourse.
On a side note: I never did see her episode on that wedding show. That would have been very interesting to watch. And again, congratulations Grey! And know that you have full love and support from us Foster's fans.
