The ghost in 'Under the Lake' is a crucial plot element, representing the mysterious and deadly force that haunts the underwater base. It appears as a spectral figure, warning the crew of impending danger. The ghost's presence raises questions about its origins and connection to the events occurring at the base, driving the narrative forward as the Doctor and Clara seek to uncover the truth.

The underwater base, known as the 'Underwater Base of the 21st Century', serves as the primary setting for the episode. It is a research facility located at the bottom of a lake, where a team of scientists is investigating mysterious underwater phenomena. The isolation of the base creates a tense atmosphere, heightening the sense of danger as the crew encounters supernatural elements.

The episode introduces several key characters, including the Doctor, played by Peter Capaldi, and Clara, portrayed by Jenna Coleman. Additionally, the crew of the underwater base includes characters like Cass, the base's technician, and Lunn, a deaf character who communicates using sign language. Each character brings their own emotional depth and motivations, contributing to the overall tension and dynamics of the story.

The Doctor approaches the situation with a mix of curiosity and urgency, eager to solve the mystery of the ghost and the lake's secrets. He exhibits confidence and a willingness to take risks, often prioritizing the investigation over the immediate safety of the crew. In contrast, Clara is more empathetic and concerned for the crew's well-being, often urging the Doctor to consider the human cost of their actions. This difference in approach creates tension between them as they navigate the unfolding crisis.

The time loop is a pivotal plot device in 'Under the Lake', as it creates a cyclical narrative where events repeat themselves. This element adds complexity to the story, as the Doctor and Clara must figure out how to break the loop and prevent the tragic outcomes that have already occurred. The time loop also serves to heighten the suspense, as the characters grapple with the knowledge of their fates and the urgency to change the course of events.
