We should also mark Daddy's lecture carefully, a lecture Brick himself will come to repeat soon after. This lecture begins to elaborate the play's parallel loves, that of Brick and Maggie and Daddy and Mama. Put otherwise, Daddy is not only Brick's judge, but he is also his double. Daddy's narcissistic love for Brick is clear. As Williams notes, Brick bears the same charmingly masculine indifference Daddy must have in his youth. Brick is his would-be heir, his means of immortality. As Mama will note at the close of the play, Daddy wants above all that Brick provide him a grandson who is as much like his son as Brick is like himself. The mirror relationship between them will become clearer in the course of their dialogue progresses, in which Brick and Daddy will appear through various structures of rivalry.
