i think that she will either leave sloane and sark and go back to her own organization bc between all of them and their power greedy minds(and ramabldi greedy!!) they are bound to go seperate ways(meaning im sure one of them will get killed!) but i htink that she will defiantly start her own aside from sloanes and maybe play him as well! because she is very good at being manipulative and decietful! i still havent made up my mind if i think she loves sydney(which i think she does which is alot more likely than her loving jack!) as long as their is more of this character, im happy becuase she brings soo much to the show, in amazing acting, and the plotlines, irina affects all the characters and characters relationships(ie, sydney and jack, vaughn and jack, jack and vaughn, vaughn and sydney, and all of them alone too, not to mention the rambaldi prophecy!!
