1. Crooks asks if he might be able to join Lennie, Candy, and George on the land they are planning to buy. He says that he would be able to do odd jobs and help, but later changes his mind (likely because of his interaction with Curley’s wife). 

Chapter 5: 
1. Lennie accidentally kills the puppy Slim gave him. 

2. When Curley’s wife comes into the barn while Lennie is alone, Lennie originally refuses to engage beyond saying he shouldn’t talk to her. Eventually though, Curley’s wife gets him to feel how soft her hair is. When Lennie doesn’t want to let go, Curley’s wife starts panicking. She starts screaming, and Lennie tries to keep here from making noise (he doesn’t want George to decide he can’t tend the rabbits) but ends up snapping her neck. 

3. Lennie follows George’s directions and leaves the barn to hide in the brush until George can come for him. 

4. Candy discovers that Curley’s wife is dead. He first shows George who knows it was Lennie’s doing and then waits to alert the others until George has returned to the bunkroom so that George doesn’t seem guilty. Curley and the laborers decide to start a lynching party, and George is forced to participate. 

Chapter 6: 

1. George finds Lennie and while he distracts Lennie with talk of their plans for their own land, he shoots Lennie in the head. Before he does so, George also apologizes for all the times he got mad and is clearly heartbroken over his decision (thought Lennie fails to pick up on George’s sadness). 

George and Lennie have a vision of their perfect life: getting a place to stay they can call their own. This is one of the only things Lennie can remember, and the book follows their journey on reaching that goal.
