As shocked and upset as I will be if Casey were to leave Chuck, I am afraid it could very well be the case.
In two recent posts, Michael Ausiello revealed that Casey does something in episode 10 of season 3 that "could-cost-him-his-job". He then says it is connected to his earlier post where he revealed Robert Patrick from T-1000 will be joining the show mid-season.
Does that mean Casey gets the boot and Robert becomes the new NSA guy protecting Chuck?
I hope not!
