Yep. There will be tension of varying sorts.
I don't know if I've mentioned it before, and I'm not really keen on spoilers, but Surayah will not leap forward and announce she is Saerk Farrahd's daughter until the situation reaches a head and Anomen has to make a decision. (And I am trying to leave some wriggle room here so the PC can decide whether her motivations for keeping silent were trustworthy or not.) Between being a follower of Sune and from Calimshan, Anomen still knows enough to be critical of Surayah, and he is. The first several talks they have serve to build cameraderie between the two, and the course that follows also relies on the direction Anomen takes at Moira's death, as well as the status of an Anomen-PC romance. The focus and degree of conflict between the two is going to depend on the path you take in the game.
