What detail is added to the Weed story when George confides in Slim?

George confides in Slim about what transpired with Lennie in Weed> H told Slim that when Lennie touched the girl's dress she started screaming. Lennie was so frightened that George actually had to hit him with a fence post in order to get him to let go of her. Unfortunately, the girl understandably upset took her accusations a step further and rather than just state the truth claimed she had been raped.

the reson that was added was that lennie was gone and george had done it
