I have been bullied too, just in case you may think I 'don't get it cause i've never been there'.
And still I see what Pepe did as false.
If it would have been Carter finally growing a pair, then, yes, it would have been bordering awesome.
As for the cheating.
Well, maybe it wasn't intentionally, but it doesn't take much to construct something out of the facts that of all rules the wizards kept that (and a few others we never here about because they are apparently not important) one in, a servant to the wizards carrying a jersey for Trevor, who has some reputation of being incredible at kicking the can, AND an empty tin can in her back and that the ball goes missing almost directly after trevor entered the game, is replaced by said tin can that was brought along by the servant to the wizards and AM United not being given a chance to actually adjust to the new 'ball'
Really, it does not take much.
EDIT: BTW, I think an even more unsettling trend is the combination of feces and sex in the past few books.
A scene from Thud everyone remembers (and I, who haven't it read yet constantly stumble over) is Angua and Sally ('twas sally, wasn't it) naked in the sewers.
In Making Money we get this whole sextoy/S&M stuff and Harry King in a sorta major role that fulfills actually no purpose that would have required someone who's business is, well, sh*t.
UA is a bit more subtle about it, but when I see a toilet IN a bed (no matter how sleepy/lazy one is, there's a gaping difference to a simple chamberpot), some of the picked, longwinded 'insults' centering around sh*t and all these pretty flat, but present sex-jokes (not to mention the absolut unnecessary information that lady margolotta (most likely her) now has a rubber-fetish-dress) sum up to the same.
Can't speak for Snuff yet, but from what I do know about it so far... The same sh*t again.
THAT is unsettling.
Not saying that 'literature has to be kept clean', hell no, it's just the amount of it and scenes that seem to be soley there for the lines about one of both.
