Identify Slim and Carlson.

Carlson

A large, big-stomached man who works at the ranch, Carlson complains about Candy's dog and eventually offers to put the old dog out of its misery. George steals Carlson's gun to shoot Lennie after Curley's wife is murdered.

Slim

The jerkline skinner at the ranch, Slim is a seemingly ageless man who carries himself with great gravity. He gives Lennie one of his new litter of puppies to care for. Curley initially suspects that his wife is having an affair with Slim.
