One of Carruthers many talents is keeping a sharp eye on the use of Americanisms in English. Unless we could train a dog to recognise "defense" rather than "defence", for instance, and then judiciously apply the necessary punishments, then our language would deteriorate even more rapidly, which I'd be loath to see. Carruthers can sometimes be a bit over-enthusiastic in his use of thumbscrews or the Cat o' 9 Tails, so maybe a spell in the wheel himself would give him a chance for a recalibration. I'll think the issue through.
