Belinski's agenda...
Adam Belinski makes a play for Betty Cream on the pretense of counseling her regarding the need to marry the Lawford character.
But she knows his agenda. His hair is combed and he's wearing a dose of cologne. He was making a pass.
He is rebuffed, and the next day he gives notes, leaves, and proposes to Cluny Brown on the train.
In my view, Cluny was his second choice. "The Honorable Betty Cream" was his first.
