What is the plot?

Vikram begins the episode trying to force a return to 1847 with a homemade time machine built from powerful Library artifacts, driven by his longing to go back to Anya and undo the life he has made in the present. The attempt goes wrong immediately, and instead of sending only Vikram to the past, the device drags the entire team out of the present and into the age of King Arthur, depositing them in 847 AD.

The group lands in unfamiliar medieval territory and is quickly disoriented by the harshness of the era and the danger of being strangers with no protection or resources. Their confusion deepens when they realize they are not in a safe or mythic version of Camelot, but in a brutal historical moment where survival itself is a problem.

They soon encounter a younger version of Mrs. Astolat, known in the present as Elaine. She is wary, defensive, and clearly hiding something, and the team's first exchanges with her are strained because she does not know them and does not trust them. The group begins to understand that this version of Elaine is guarding a magical shield and is afraid of Lancelot, who is hunting it.

At the same time, the time machine is taken away from the group, leaving them stranded in the past with no immediate way home. Their situation becomes even worse when local forces and soldiers treat them as intruders and capture them. The team is taken prisoner and confined, with their escape route cut off and their ability to influence events reduced to almost nothing.

Inside captivity, the team comes face to face again with Elaine, and the confrontation forces them to try to persuade her that they are allies from the future. Their efforts do not immediately succeed, and Elaine remains guarded because the stakes around the shield are much larger than the team initially understands. She is not simply hiding from Lancelot for herself; she is protecting an object whose possession could shift the balance of power in the era.

The group then has to endure the practical misery of imprisonment while Lancelot closes in on the shield. The danger escalates as they remain trapped, unable to prevent the confrontation they know is coming. Their capture also leaves them vulnerable to punishment, because in this setting they are seen as outsiders and potential enemies rather than accidental time travelers.

Lancelot eventually catches up with them and takes control of the situation. He prepares to have them burned at the stake, turning the team's imprisonment into a public execution threat. The scene becomes a direct confrontation over the shield and over who will control the fate of the people caught in the middle of the conflict.

At that moment, Elaine makes a decisive move and reveals herself in full armor. Rather than remain hidden, she steps forward and demands a one-on-one duel with Lancelot. Her decision changes the entire shape of the conflict, because she chooses personal combat instead of letting the team be killed as bargaining chips.

Elaine fights Lancelot directly and defeats him without using the shield itself. Her victory breaks his immediate hold over the situation and saves the team from being burned. The duel also establishes that she is not simply a passive guardian of the shield; she is a capable and decisive warrior willing to confront Lancelot on her own terms.

After Lancelot is beaten, the episode resolves with the team's immediate survival secured and the medieval crisis temporarily defused. The surviving characters are left in the altered past with the knowledge that their accidental time jump has brought them into the true history of Arthurian legend, with Elaine at the center of events and the danger around the shield finally brought into the open.

What is the ending?

Vikram's time machine goes wrong and sends the whole team back to King Arthur's era, where they get caught up in the hunt for a magical shield and the conflict with Lancelot. In the end, Elaine/Mrs. Astolat defeats Lancelot, saves the team, and gives Vikram the shield so he can return it to the Library, while Vikram and the others leave the past behind.

At the start of the ending, the team is trapped in Arthurian times after Vikram's homemade machine misfires and lands them in 847 AD instead of 1847. They discover that the young Mrs. Astolat is alive in this period, hiding from Lancelot, who is pursuing a magical shield. The group is captured, and Lancelot prepares to burn them alive.

Then Mrs. Astolat arrives in armor and challenges Lancelot to single combat. She says she has already beaten him before, which explains why he erased her name from Camelot's records. Lancelot accepts the duel, and in the fight Elaine breaks his helmet and knocks him down. Humiliated, he orders his men to kill her, but Charlie grabs the shield and brings it to Elaine.

Elaine uses the shield's power to drive off Lancelot's men and save the team from the fire. She tells Lancelot that by breaking his oath, he is no longer a knight. Lancelot loses his honor in that moment and walks away, promising to return someday.

For the main characters' fates at the end: Vikram survives, leaves with the others, and receives the shield from Elaine to take back to the Library. Charlie survives and helps save the group by securing the shield for Elaine. Lysa survives the ordeal and leaves the past with the team. Connor survives and returns with them as well. Elaine remains in the Arthurian past after the confrontation, having reclaimed her place as a powerful protector in that era.

Is there a post-credit scene?

There is no source in the results that confirms a post-credit scene for episode 10, so I cannot verify that one exists from the available evidence.

What the available materials do show is that episode 10, "And Going Medieval," is the season finale and that it centers on Vikram's attempted time travel, which sends the team back to King Arthur's era, where they uncover more about a Knight of the Round Table, Camelot, and Elaine.

If you want, I can help you check whether the episode has a separate tag scene, end-credits button, or post-credits stinger by comparing recap/review coverage.

What are the consequences of Vikram's decision to use the Library's artifacts to build a time machine in episode 10?

Vikram's impulsive decision to use iconic artifacts from the Library to build a time machine leads to him traveling back in time, which causes significant narrative twists and emotional stakes. This act pulls Charlie, Lysa, and Connor along with him, unintentionally sweeping them into a past that could potentially upend everything they know.

How does Vikram's character conflict with the Library's code of conduct in this episode?

Vikram, being a man out of time from the 1800s, has often clashed with the Library's rigid code of conduct. Unlike others who adapted, he has quietly resisted the system, and his decision to time travel reflects this ongoing tension between his heart-driven impulses and the Library's rules.

What new revelations about Mrs. A are revealed in 'And Going Medieval'?

Mrs. A's truth comes out during the episode as Vikram's time travel goes awry, revealing deeper layers to her character and her role within the story.

What are some notable character moments or performances highlighted in episode 10?

Philip Rosch's performance was praised as perfect, and Elaine received more screen time than ever before, which was well received. However, some moments, such as Charlie referencing unseen conversations and the handling of the Pentecostal Oath, were noted as detracting from the episode's immersion.

How does the episode address the public's awareness or reaction to magical phenomena?

The episode, and the season overall, features very public magical events such as a werewolf-like attack and a runaway train on nonexistent tracks. There is curiosity and some concern about how the public reacts to these events, especially since there is no clear discussion of magical coverups or memory wipes happening within the story.

Is this family friendly?

Yes--this episode is generally family-friendly for older children/teens, but it is rated TV-14, so it may be a little intense for younger kids.

Potentially objectionable or upsetting elements to expect: - Fantasy peril and danger involving the whole team being sent into a medieval setting, which can include suspense and threat. - Mild violence or action-fantasy conflict, since the series' parental guidance lists violence/gore as mild. - Mild profanity may occur; the parental guide notes some curses across episodes, including words like "damn," "hell," and "shit." - Mild frightening/intense scenes, which may bother sensitive viewers even if the episode is not especially graphic. - Brief romantic content appears elsewhere in the series, including kissing and implied sex, so this show may not be ideal for very young children depending on parental standards.

If you want, I can also give a more conservative age recommendation like "OK for 10+ / 12+ / 14+" based on the available content signals.
