I remember Soren was in the heart of the Daimon invasion and destruction of Heen in 4th invasion. He's also a bit touched in the head at this point. I don't think the Daimons scare him so much anymore. I'd love to keep RPing some stuff with the Daimons, but 1st Son just sort of laughed at him last time (not that I blame him).
Though really, despite the hints Tom says we know, I don't think anyone realizes that they're hints because no one has put anything together thus far...
