Answer :
Dexter's reaction to Devlin's comments about Judy's declining beauty highlights his deep attachment and idealization of her, which is tied to his self-identity and youth.
The emphasis on the word pretty and Dexter's reaction to the changing perception of Judy's beauty reveal his deep attachment to her, painting a picture of an idealized and unchangeable beauty in his mind. When Devlin describes Judy as simply 'all right,' it not only diminishes Judy's beauty in Dexter's eyes but also suggests a loss of the ideal he worshipped. Dexter's desire to get very inebriate reflects his profound disillusionment and the emotional impact the news of Judy's situation has on him, indicating that his attachment to her may be tied to his own self-identity and the dreams of his youth that she embodied.
