Maleficent was other than forced to walk along with her companions towards the gate of the Halls of the Woodland Realm. The fae may be have the respect for the elves, but she didn't appreciate herself being dragged by them. The ElvenKing was another story to her. She knew him, but she really watched him from a distance. She remembered Legolas when he was just a young elfling, when she, again, was watching him from a tree. They did cross paths once or twice unintentionally, but she doubted that the prince would understand, or even remember who she was, minus her newly added horns and wings. 

The fae was surprised that she wasn't the one being taken to the dungeons like everybody else, except for Thorin. She did keep her eyes on Legolas, though.
