I am on the fence now LOL.  Who should Ibis be with?  Stephen  which is her own kind.  I know Stephen can be a jack@ss but like Syliva  he is doing the wrong thing and it is because he doesn't like being alone.  There is a side of Stephen that made Syliva choose to make Stephen who he is now.  So mabe there is something about Stephen that is good and you just have to find it.  Syliva also said if I am not mistaking that Stephen could be in love with Ibis.  Or Will a human.
