Zephyr, Quinton, and Elara are in a library. Zephyr leaves her notebook on a table and goes to the history section to look for a book. While she's away, Quinton comes by, sees the notebook, and thinks it belongs to Elara, so he hands it to her. Elara knows it isn't hers but believes it's Quinton's. She accepts it and puts it inside her backpack. When Zephyr returns, she can't find her notebook and asks Elara if she has seen it. Elara, thinking it's Quinton's, lies and says she hasn't seen it because she doesn't want to upset Zephyr by revealing that Quinton made a mistake. Later that day, Quinton tells Zephyr he gave her notebook to Elara. Zephyr confronts Elara, who is now confused because she learns that the notebook was Zephyr's all along. Who does Elara think is upset with whom, and why?

Provide a brief response.
Elara believes that Zephyr is upset with her because Elara earlier lied to her about not seeing the notebook. When Quinton tells Zephyr that he gave Zephyr's notebook to Elara, Zephyr likely believes that Elara knew the notebook was Zephyr's when she denied seeing it, which could cause Zephyr to feel betrayed or deceived by Elara's lie. Therefore, Elara would logically conclude that Zephyr is upset with her for lying about the whereabouts of the notebook, not knowing that it actually belonged to Zephyr. Moreover, Elara also may think that Zephyr is upset with Quinton for mistakenly giving the notebook to the wrong person, causing the entire mix-up. Elara does not have any reason to believe Zephyr is aware of Elara's initial belief that the notebook was Quinton's, which further contributes to her confusion and her belief that Zephyr is upset with her for lying and possibly with Quinton for his mistake.
