Final answer:
The question seems to be about a literary character's actions causing panic, but without more context or a direct mention of Lissas, it remains unclear. The provided excerpts allude to various dramatic actions causing shock or distress which may resonate with the theme of the student's question.
Step-by-step explanation:
The details provided suggest the question is about actions of characters in certain dramatic or suspenseful moments in stories, likely from literature classes. Lissa is not mentioned directly in the excerpts. Diana's panic could be a result of the actions of another character in a similar setting, which causes a significant emotional or plot reaction. However, based on the unnamed characters and their actions that caused panic or serious reactions—such as a sudden move by Lassiter, Jane's realization of Lassiter's unsettling change, or the intense scene with the lions—it can be inferred that actions triggering fear, anxiety, or a major turning point in the story may be the central theme here.
