Hook’s going to be a regular for the last 9 episodes of season 2 so that’s when it’ll probably start kicking off between him and Rumple. Belle’s not really been involved in the main plots of the season so far. They’ve so far seemed to concentrate on Emma and Snow in fairytale land and Charming trying to get them back. All other characters were pushed to the side. Hopefully with Emma and Snow back in Storybrooke, along with Cora and Hook, other characters outside of the Charming clan will now get a chance to shine.
