The New Discworld Companion wrote:Vetinari, Havelock, Lord.
Probably his greatest enemy is Commander Sir Samuel Vimes of the City Watch but, strangely, the person with whom he gets on the best - or least badly - is Captain Carrot Ironfoundersson of the same Watch. They share the same obsessive interest in the city itself.
The above quote from the New Discworld Companion got me thinking. I don't think that Sam and Havelock get on, but "enemies"???
What do you think of their relationship?
