Charlie, Lysa, and Connor are unexpectedly transported through a magical door to a mysterious manor where a series of Agatha Christie-style murders are occurring. Upon arrival, they find themselves in a lavish setting filled with quirky guests, food, and drink, but the atmosphere is tense and strange. They quickly realize that the manor and its inhabitants correspond to the major arcana of a tarot deck, with characters embodying cards such as the Fool, the Magician, the High Priestess, the Lovers, and the Hermit. The team begins investigating the murders, noting that the killings are happening in the order of the tarot cards.

Meanwhile, Vikram is separated from the group and finds himself in a different, empty, and dusty version of the manor. He struggles to find a way back to his friends and discovers that the manor is actually a magical prison designed centuries ago to contain an aspect of the Devil. The prison's enchantment is maintained by three keepers who represent the Fool, the Magician, and the High Priestess. If all three keepers are killed, the Devil will be freed.

Back in the manor, the librarians race to identify who among the guests are the three keepers and to protect them from the killer. They suspect Princess Lucille is the High Priestess. The Tarot reader, Madam Visconti, appears as a mysterious figure who moves between the two realities and helps the team understand the nature of the murders and the prison. The team learns that the Devil card in the tarot deck represents the actual Devil trapped in the manor, who has already killed two of the three keepers and is close to escaping.

As the murders continue, the librarians piece together that the Devil's plan is to use the deaths of the keepers as sacrifices to break free from the prison. The tension rises as the team tries to prevent the final killing that would release the Devil. Vikram, understanding the stakes, realizes that a sacrifice is necessary to reset the prison's enchantment and keep the Devil contained. In a heroic and dangerous move, Vikram enters the other realm of the manor and sacrifices himself, which triggers the prison to reset. After this sacrifice, Vikram returns to the real world alive, having effectively thwarted the Devil's escape.

The episode ends with the librarians safe, the Devil still imprisoned, and the manor's magical prison intact, but the experience leaves the team shaken and aware of the high stakes involved in their mission. The story emphasizes sacrifice, trust, and transformation as key themes throughout the episode.

At the end of "The Librarians: The Next Chapter," Season 1, Episode 6, "And the House of Cards," Vikram sacrifices himself by entering the Devil's prison realm to reset the trap and prevent the Devil from escaping, ultimately returning to life in the real world while the rest of the team remains trapped temporarily in the supernatural house.

The episode unfolds with the team--Vikram, Lisa, Connor, and Charlie--caught in a mysterious house that exists in two vastly different realities. Vikram finds himself in an empty, dusty version of the house, while the others are surrounded by food, drink, and quirky guests, all part of a murder mystery setting. A Tarot Card Reader moves between these two realities, serving as a bridge and revealing crucial information about the nature of the house and the true antagonist.

It is revealed that the house and the Tarot deck are actually a prison for the Devil, who is attempting to escape their immortal chains. The Devil's plan involves luring the heroes into this realm to obtain a powerful knife, with the escape requiring three sacrifices. Vikram, understanding the stakes, realizes that sacrifice can instead reset the prison and keep the Devil confined indefinitely.

In a pivotal and tense moment, Vikram enters the Devil's realm alone and sacrifices himself. This act triggers the prison's reset mechanism, thwarting the Devil's escape plan. After this sacrifice, Vikram returns to the real world alive, marking a heroic and transformative moment for his character.

Meanwhile, the rest of the team--Lisa, Connor, and Charlie--remain trapped in the supernatural house, caught in the Devil's machinations. Vikram's return to life contrasts with their ongoing predicament, setting up future challenges for the team.

There is no information in the available sources indicating that The Librarians: The Next Chapter Season 1, Episode 6 ("And the House of Cards") includes a post-credit scene. The detailed recaps, previews, and episode descriptions focus on the main story involving the team separated by magical means, a murder mystery mansion, and the Devil trapped in a Tarot prison, but none mention any scene after the credits. The Wikipedia entry and other summaries also do not note a post-credit scene for this episode. Therefore, it appears that this episode does not have a post-credit scene.

In episode 6, the Tarot cards, particularly the 'Devil' card pulled by Madam Visconti, symbolize the actual Devil trapped in a murder mystery mansion. The cards serve as a key to understanding the supernatural threat the team faces, as the Devil has been killing those who imprisoned him, creating a race against time for the Librarians to stop him before he kills the last offender.

The team members each question different guests: Connor interrogates Mortadella, Vera, and Phillip, while Lysa questions Yvette. This interrogation is part of their investigation into the murder mystery mansion and the Devil's killings, aiming to uncover clues and prevent further deaths.

Episode 6 highlights tension between Vikram and Lysa, particularly through an argument that reveals their strained relationship. Lysa is shown to be learning more about the world and has a personal stake in the events. Vikram's connection to Lysa is complicated by her link to his deceased lover from 200 years ago, adding emotional depth to their interactions.

The murder mystery mansion is the prison where the Devil is trapped. It serves as the central setting for the episode's conflict, with the Devil killing the offenders who imprisoned him. The mansion is both a physical and magical containment that the Librarians must manage to prevent the Devil from escaping and causing greater harm.

Episode 6 foreshadows further development of the Devil character, suggesting she will become stronger and more aware of the Librarians' efforts to contain her. It also hints at the need for Vikram to confront his past, particularly his conflict with Gregor and the unresolved history from the 1800s, which is expected to be explored in future episodes through flashbacks and confrontations.
