Final answer:
The question relates to themes of deceit, murder, and betrayal explored in literary texts, which fits within the scope of an English class, specifically high school literature studies.
Step-by-step explanation:
The excerpts provided seem to stem from literary sources that deal with themes of deceit, jealousy, and moral dilemmas, like murder and betrayal. These themes are often explored through character interactions and dialogues, which is evident in phrases mentioning the murder of a character named Jessica, or the killer being part of a company. It's clear that these are narratives from stories, possibly novels or plays, where characters are grappling with heavy emotional and ethical issues.
Such content would typically be discussed in English classes, particularly in those focusing on literature, which is often part of the curriculum in high school. Students are encouraged to analyze and interpret the text, develop an understanding of thematic elements, and explore character development within these narratives.
