After watching the finale of the 4th season, I had just one question to the screenwriters:
Where is Catelyn Stark?
AFAIK, the book shows us
Her being resurrected at the very end.
Instead, we just see:
The death of Tywin Lannister and the escape of Arya Stark.
So, did HBO producers give any official disclaim? Will this character appear at least in the 5th season?
