What are some examples of direct/indirect characterization concerning Carlson? John Steinbeck's Of Mice and Men

A flat
character who does not change throughout the narrative of Steinbeck's novella
, Carlson is developed through indirectionrather thanwhich involves direct
statements giving the writer's opinion of the character.  Here are the ways that Steinbeck does
use :

through a physical description of the
character

In Chapter Three, Carlson is described as
"thick-bodied" with a "heavy-legged stride."

through the character's thoughts, feelings, and
speeches

Carlson demonstrates his arrogance and insensitivity
in a number of ways.  First of all, when he enters the bunkhouse, he assumes everyone thinks it
is dark and turns on the second shaded light, commenting in the same breath about the dark in
conjunction with the ranch hand with dark skin:

"Darker'n hell in here," he said.  Jesus, how that n--- can pitch shoes....He
don't give nobody else a chance to win--"

Then, he
snifs the air, locating the odor as that of Candy's old dog:

...Get him outa here, Candy!  I don't know nothing that stinks as bad as an old dog. 
You gotta get him out."

Ignoring Candy who
"squirmed uncomfortably" and "looked helplessly" at Slim for some
"reprieve," Carlson offers to shoot the dog for Candy.  When he sees Candy's
discomfiture, Carlson callously explains that he will kill him so that the dog will not
"even quiver."

"If you want me to, I'll put
the old devil out of his misery right now and get it over with.  Ain't nothing left for him. 
Can't eat, can't see, can't even walk without hurtin'." 

Then, when Whit enters and shows Slim a magazine with a letter from a former bindle
stiff there, "Carlson had refused to be drawn in" to the conversation, indicating his
unfriendliness and self-imposed alienation.

Of course, Carlson's
insensitivity reaches its magnitude after he arrives at the river bank wherelies dead in Chapter
Five as Slim consoles . 

Curley and Carlson looked after
them.  And Carlson said, "Now what the hell ya suppose is eatin' them two
guys?"

through the character's
actions

Despite Candy's anxiety, Carlson takes the swamper's
old dog and shoots him with his Kruger in Chapter Three. In the final chapter, Carlson eagerly
runs for his gun as the men prepare to find Lennie and kill him.  But, Slim reaches the river
bank before them, and consoles George after learning of Lennie's death. "Curley and Carlson
looked after them," puzzled. 

through the comments and
reactions of other characters

Interestingly, there are no
reactions to Carlson as he stays out of any interaction in two instances:  in Chapter Three when
Whit shows Slim the letter from William Tenner, and in Chapter Five as the men rush in to see
Curley's wife lying dead on the hay, Carlson keeps back "out of attention
range."  Nor, are there any comments made about Carlson's personality. When Curley mentions
him, it is only to say that his Kruger has been taken.  

From these methods
of characterization, the reader comes to realize that Carlson is representative of the alienated
men who become hardened, insensitive, even cruell to others.
