The question was posed as to whether Delly embodies a “disruption of normative discourses”. Frankly, I don’t like this question. Perhaps I’m misreading it but to me it places too much agency on a character who does next to nothing in this short story, and the type of agency it gives him is not consistent with this character.
The only thing Delly really does in the narrative is sing. Most of what we learn about him is described by his father. It’s hard for me to say Delly embodies anything when he’s really just a background character, a personification of his father’s homophobia. In fact, I don’t recall even learning Delly is gay. I remember he plays with dolls, enjoys theatre, dislikes football, but that ultimately means nothing.
I don’t think it’s productive to focus on a character with such little characterization, but rather analysis should be focused on the father who jumps to conclusions about his son because of fear and hatred, even going as far as to disrupt the recital at the end.
