What foreshadowing is in chapter 2 Of Mice and Men?

The main theme would be Curley's wife's appearance.

She wears all red, which instantly foreshadows danger, and portrays her as a sexual woman, which is how she was seen by most men on the ranch.

You can link this to the woman in Weed. Lennie grabs her red dress and she cries for help and gets away. This could show Curley's wife is in danger, or will cause trouble like the woman in Weed did for Lennie and George - which she does.
