Sothe

Sothe was the first character of the Path of Radiance cast that was announced to return in Radiant Dawn. After The Mad King's War, Sothe returned to Daein's capital of Nevassa, found Micaiah, and expressed how upset he was that she had abandoned him. As a result, Micaiah realized how important she was to him, and she swore to never leave him again.

However, Sothe and Micaiah continue to have their disagreements. Throughout most of the game he argues with her, mainly over Sothe's strong respect for Ike, whom Micaiah views as responsible for destroying Daein in The Mad King's War. Nevertheless, he is very protective of her, and he stays by her side during their battles against Ike.
