More insight into Rathkor: Ever since this ordeal with Tyrdin's began, he has felt as if we were being led into a trap. For a group of clandestine Satan worshipers, several of their actions seemed to be leading the Louts closer and closer. The mother is serving as bait, the various breadcrumbs almost blatantly leading us straight to them, Rathkor doubts they are sloppy. He is worried about being led into an ambush. Normally he would not involve himself in an obvious trap, but he knows Tyrdin will go with or without him, blinded as he is by his rage. Rathkor has begun to like Tyrdin, and even sees him as a friend. He does not want to see anything bad happen to his friend, so he has decided to tag along and try to act as the voice of reason to balance out Tyrdin's rage.
As for his feelings on the rest of the group at this point, he distrusts the shadowman and questions his motives(which means nothing now that shawn is gone.), He thinks Falagar is an idiot who manages to pull of some truely amazing feats from time to time, but ultimately wouldn't care too much if something happened to him. Respects Helga's combat abilities and has seen hints of a softer side. Thinks Sylvaria is creepy, but still does not want to see any harm come to the child.
