Answer:
In the passage from "Their Eyes Were Watching God," by Zora Neale Hurston, Janie and Tea Cake have spent the night together. Thus, the passage reveals Janie's inner conflict regarding Tea Cake: she has feelings for him but she is not sure about him. Besides, she feels secure when he is around; however, when he is gone she is invaded by doubt.
The tone of the passage is premonitory, as if something bad were about to happen, such as Janie being abandoned again and being desolated. The fateful tone is indicated by the coolness of the morning, which is contrasted with hell. Besides, the author mentions words like "attacked" and "excruciating," which have a negative connotation, and also refers to an "abyss" when describing Janie's emotions of insecurity.
