Add some more details to what you know about Candy and Carlson.

Candy:

An old, crippled man who has lost his hand, Candy is the swamper at the ranch. He remains attached to his aging dog, who has become so weak and sickly that it depends entirely on Candy to survive. Still, when Carlson objects to the dog's smell, Candy allows Carlson to put the dog out of its misery. Candy is a passive man, unable to take any independent action. Indeed, his one major act in the book - when he offers Lennie and George money in order to buy a piece of land with them - is a means by which he can become dependent on them.

Please ask about each person in a separate question. Thanks.
