When the boss is talking to George about their work, George speaks for himself and Lennie. What does his boss suspect is going on between George and Lennie? What is George's response?

His boss suspects that George is taking the pay away from Lennie when they get their money. He believes that George is "staking" Lennie and watching him secretly. George's response to this comment is he tells the boss that he is Lennie's cousin. He says that he is taking care of Lennie because Lennie's mom told him to. He also said Lennie got kicked in the head when he was a kid, so he is a little dumb, but still a great worker.
