In some ways being called Prince is more flattering than king would be because King are seen with disfavour if they make bad choices and they are the ones who are blamed if something goes wrong.
They can also be manipulative and dictators, where as Princes are not seen in the same light.
The narrator is omniscient and ‘talks’ in the third person and it is still supporting the positive view of Slim.
‘Prince of the ranch’ is ‘spoken’ by the narrator and is consistent with the overall image of Slim which Steinbeck offers us.
Steinbeck portrays him as having natural authority and prestige.
Steinbeck shows Slim as a very respected character in the novel, ‘all talk stopped when he spoke’ the other characters are so keen to listen to whatever Slim might say that they simply stop so they can hear because he is the most important ranch worker.
At the start of the novella, George is something of an idealist.
Despite his hardened, sometimes gruff exterior, he believes in the story of their future farm that he tells and retells to Lennie.
Later on, Steinbeck again suggests this with, ‘that dog ain’t no good’ because he is yet again supporting the death of a dog.
Slim does act on good intentions though; he drowned the puppies because ‘She couldn’t feed that many’ and they would probably have died anyway.
