Hm, the forums ate my earlier post...<br/><br/>Right now, my general rule is that whenever someone has to make a roll out of turn, I'll roll for them unless they post a roll first.  In this case it wouldn't have mattered (aside from my dice hating the PCs), since Guts was next anyway, but if for example Valorie gave him a saving throw, I'll roll it so that we don't have to wait for Zaer to come in, post one roll, and then go to Varis.  (If an out-of-turn roll isn't mandatory and has some sort of drawback, I'll let the player make it when they decide whether or not to use it, of course.)
