'You two start on home, Daisy,' said Tom. 'In Mr. Gatsby's car.' She looked at Tom, alarmed now, but he insisted with magnanimous scorn. 'Go on. He won't annoy you. I think he realizes that his presumptuous little flirtation is over.'

‘You two start on home, Daisy,’ said Tom. ‘In Mr. Gatsby’s car.’
She looked at Tom, alarmed now, but he insisted with magnanimous scorn.
‘Go on. He won’t annoy you. I think he realizes that his presumptuous little flirtation is over.’
