Of Mice and Men Section 2

In section 2, George and Lennie went to find a job, they met their boss and his son, Curley, and his wife, they also met their colleagues, Candy and Slim. They all have very different personalities. Candy and Slim are very nice to George and Lennie, different than them, Carlson, Curley and his wife are very mean to them. I saw some foreshadowing in this section, one is that George want Lennie always to remember to hide in the brush by the river to wait for George to arrive if he get into any trouble, why down in the brush? Is Lennie still going to get into troubles? Another foreshadow in about Candy's dog, Steinbeck described his dog specifically, "And at his heels there walked a drag-footed sheep dog, grey of muzzle, and with pale, blind old eye. The dog struggled lamely to the side of the room and lay down, grunting softly to himself and licking his grizzled, moth-eaten coat. The swamper watched him until he was settled." I thought that there is something similar between Candy's dog and Lennie, Steinbeck wrote that Lennie dragged his feet a little when he walks, just like Candy's dog. They are both someone who cumbers someone that cares for them. If Candy's dog represent Lennie, than at the end of section 2, is Steinbeck trying to tell us that something is going to happen between Curley and Lennie? Candy's dog also represents Candy when Carlson asked that why can't they just get rid of  the dog because he is too old, he can't do any thing anymore, that is what Candy's afraid of because he is also old, he don't want the boss to fire him and hire someone that is young and strong, he wants to be a part of the ranch. My character is Slim, so I payed the most attention on him. According to section 2, he appeared after Curley's wife went for looking for Curley. "A tall man stood in the doorway. He held a crushed Stetson hat under his arm while he combed his long, black, damp hair straight back. Like the others he wore blue jeans and a short denim jacket. When he had finished bombing his hair, he moved into the room, and he moved with a majesty only achieved by a royalty and master craftsmen. He was a jerkline skinner, the prince of the ranch, capable of driving ten, sixteen, even twenty mules with a single line to the leaders. He was capable of killing a flu on the wheeler's butt with a bull whip without touching the mule. There was a gravity in his manner and a quiet so profound that all talk stopped when he spoke. His authority was so great that his word was taken on any subject, be it politics or love." He is really nice and polite to George and Lennie and he have a dog named Lulu who just slang nine pups, he drowned four because Lulu can't feed that many. George and Lennie are very happy and exited because they might get to have one or more puppies from Slim. Will he help George and Lennie in the future?
