If all Porre did was study him, why did he turn into a mutant freak?
Also, the party knows the other two Xamoltan and are apparently on good terms with them. Why would they not be at least bothered by the fate of the third- even if their interactions no longer technically occurred at all? Even if it were somebody they didn't like, I'd expect at least a "they didn't deserve that/even that went too far" kind of reaction. I agree with kid123 I suppose in that this chapter seems incomplete and unpolished, which is to be expected.
