Question About Tan Jala

Hey guys! (Yet again...) I had a quick question for you and was hoping one of you could answer it. In Avatar: The Game, Tan Jala is the leader of the Tipani Clan, and Sänume is the clan's Tsahik. Does this mean that Tan Jala and Sänume are mated? I thought that a Na'vi clan's leader and it's Tsahik were mated for life, as Eytukan and Mo'at were, and Neytiri and Tsu'tey were supposed to be. If so, should we change the Tan Jala and Sänume articles? Just curious.... Thanks! :)
