Lincoln
Lincoln enters the play for the first time dressed as Abraham Lincoln. It's an ironic vision that creates a moment of magical surrealism, in that it is too strange to believe.
Final Cry
Booth has just killed his brother and picks up his lifeless body. The imagery of Booth crying out after killing his brother shows that he doesn't understand the consequences of his actions before setting them in motion. That his life is dictated by his emotions first and his heart and brain must catch up to what happens.
In the Shadows
Lincoln has come home to an empty house and he counts his winnings from his hustle that day. Once he relaxes Booth comes out from behind a door. He's been there the entire time. The imagery creates the environment of danger amongst brothers.
Date Night
Booth has put up new curtains, there's food ready, champagne on ice and he is wearing a new suit. He's waiting for Grace to arrive. The imagery shows that Booth does have love in his heart; he does have a desire for more, but it's just not in the same way as Lincoln. Booth's desire is from his heart.
