First, some have assumed that the Forsaken knowledge of the capture of Semi by Rand came from either Elza or another BA in Rand's party. I don't think it can be ruled out that a DF Suldam could have also been the party who reported the encounter to the Forsaken. (yes, Suroth stated that few DF suldam existed, but it is possible that Semi had one of them with her)

Second, I was left a bit incredulous at Faile's ability to slip away from Perrin so easily again. I mean, isn't one of her forays away from him how the three book Odyssey, aka The Hunt for Faile, began in the first place. Given Perrin's personality, I find it rather hard to believe that Faile could have easily slipped away from him AGAIN to go off and take out Masema.
