When I said that they had planned CS since Season 1, I didnt mean that it was stated. In a season 2 episode, there was Hook’s hand in Rumples’ castle. This means that they planned to bring in Hook from the beginning. Now I believe that when they planned to bring in Hook, they also planned to put him with Emma – Hook’s story is similar to Emma (heart ripping out, trust issues etc.). They had wanted to put Emma with Hook since the beginning (they couldnt get the rights of Hook). This is why I believe that they had planned it since season 1.
