It really bugs me that they always played fast and loose with Sharon's knowledge of things. What does she say in this scene? Something like she knows that Kara is special but she doesn't know why?

BITCH, JACK INTO THE STREAM AND FIND THAT OUT, WOULD YOU?

I mean, really. I clicked on an old link yesterday randomly to a meta post that said the writers aversion to exposition left the characters incredibly incurious about things (like how the cylons physically worked, what Kara's destiny really was, etc.) and it's so true!
