Granny in thought bubble!

The Granny thought bubble is pretty much Rib's imagination come to life, sort of. The whole gang could see and hear her or at least Rib and Daniel can. She is the one who gave them their first weapon idea for killing the zombie that killed Joe. As the thought bubble she can be a link between the kids and wherever Granny is, sort of like a video chat thing. She can see what's going on where the kids are in real time as the kids can see what's going on over where Granny is, how you ask? I don't know it's a dang'd cartoon for cripe sakes.
