WHERE ARE THESE PEOPLE!?

I have been watching Game Of Thrones Season 2

and I am waiting for Jojen and Meera Reed to appear! where are they? They shouldn’t be cut off! 

I also heard that Edmure and Hoster Tully may also not appear together with Ramsay Snow (Bolton) who plays a very important part in Winterfell’s Tragedy, on A Clash Of Kings.
