Yesterday at lunch, I gave that bloody chapter another try. This time, I had the mages around them suddenly start throwing up. This will work better, I think. Gorok and Wulf know something is going on, but they can't do anything right away because they have to help the other mages. If someone were trying to steal something or escape, this would be better than something that puts the mages to sleep. This way, even the mages who don't eat the food or who aren't affected are distracted because they have to help the sick mages. And even if they aren't helping, they will certainly be distracted.
Then, once Gorok and Wulf are tuckered out after helping all those sick mages, something can happen. An attack, perhaps. Or this could be the time when Kensin tries to kidnap him -- to try to force/lure him to his side, to use him as bait against Wulf, or for some other reason. (Until the mage duel, he hadn't realized how useful Gorok should be. Now he is more likely to see him as a tool he himself can use rather than merely something he can use against Wulf. He can offer him Sovil's former position!)
