Xeno's already mentioned that it's safer to travel in groups just in case. Frankly, at this point, after having lost about half the original party, if you didn't heed this advice, I'd have to call you a moron. And unless Angus feels like an ass, he'll probably tell Kryx what is really going on.
Archy, ever heard of a white lie? You're making too big a deal out of this and spinning it way out of proportion. It's not like Xeno told a lie so that he could get Sales to give him everyting he owns. He told a white lie so that Sales could got back to meditation so that he could get his spells back and be fully rested.
In my experiences, villians aren't always as weak as they seem, those in need of rescue rarely need it, and the odds of being killed by the DM during the next encounter are often far greater than he lets on.
