What is the plot?

Saori is struck in the chest by the god-killer arrow, and the injury puts her life in immediate danger because only the Grand Pope can remove it.

With Saori dying and time running out, Seiya, Shun, Shiryu, and Hyoga are forced to continue their ascent through Sanctuary and pass the Twelve Temples in order to reach the Grand Pope and save her.

The episode centers on the discovery of Aiolos's final message, which reveals his legacy and entrusts the Knights with a sacred mission tied to what must be done next.

The message turns Aiolos's final words into a decisive turning point for the group, confirming that the path ahead is not only a battle through the temples but also a duty they must accept and carry out.

What is the ending?

Short version: the episode ends with Aiolos's final message being uncovered, and that message confirms that the Bronze Knights must continue forward on a sacred mission tied to Athena's fate.

In the ending, the story closes on the reveal of Aiolos's legacy: the Knights discover his last words and understand that he has left them a mission to carry on. Earlier in the episode, the Bronze Knights are thrown into a dangerous confrontation with Gold Knight Aiolos, then separated and forced into different locations, where they must keep fighting to survive and uncover the truth hidden inside the House of Sagittarius. The episode's ending turns that struggle into a message of purpose rather than a final victory scene: the Knights are not simply escaping a trap, but receiving a directive that binds them to the larger war around Athena.

For the main characters at the end of the episode: - Aiolos: his role is revealed through his final message; the episode frames him as leaving behind a legacy and a mission rather than appearing as an active continuing force in the ending. - Seiya: he remains one of the Bronze Knights pressing through the trial, still alive and still driven forward by the mission. - Shun: he continues through the ordeal with the others, still part of the group charged with advancing the quest. - Shiryu: he is also still engaged in the struggle, continuing the passage through the Twelve Temples. - Hyoga: he likewise survives the episode's conflict and continues onward with the others. - Saori: she is in danger at the center of the conflict, struck by an arrow that only the Grand Pope can remove, which is why the Knights' mission continues.

Scene by scene, the ending plays out like this:

The episode first sets up the immediate crisis around Saori, who has been struck by an arrow that cannot be removed except by the Grand Pope. This injury becomes the pressure driving everything that follows, because Seiya, Shun, Shiryu, and Hyoga must move through the Twelve Temples to reach the one who can save her.

From there, the Bronze Knights are confronted by Aiolos, who appears as an unexpected foe. The conflict does not remain in one place; instead, the Knights are transported to separate locations, turning the episode into a series of isolated fights and tests. In those different places, each Knight is forced to struggle for survival while also trying to understand what is really happening inside the Sagittarius temple.

As the episode reaches its end, the hidden truth becomes clearer through Aiolos's final words. The Knights uncover his final message, and the meaning of the episode shifts from combat to inheritance: Aiolos's legacy is not merely something to be remembered, but something that assigns them a sacred mission. The ending therefore leaves the Bronze Knights with purpose, Saori still endangered, and the larger journey through Sanctuary still unresolved, but now anchored by Aiolos's last message and the duty it places on them.

Is there a post-credit scene?

I could not verify any post-credit scene for this episode from the available sources, and none of the provided episode listings or descriptions mention one.

Based on the episode descriptions available, episode 4 centers on the Bronze Knights confronting Aiolos and fighting to uncover the truth behind the crisis, but there is no evidence in the search results of an extra scene after the credits.

If you want, I can also help check whether the episode has a mid-credits scene versus a full post-credits scene, since those are sometimes reported differently.

Why does Saori get struck by the arrow, and what does the Grand Pope have to do with removing it?

The episode's setup centers on Saori being hit by an arrow that only the Grand Pope can remove, forcing Seiya, Shun, Shiryu, and Hyoga to push through the Twelve Houses to save her. This is one of the most specific plot questions people would ask because it directly concerns the inciting injury and the obstacle tied to the Grand Pope's authority.

What is Aiolos’s final message, and how is his legacy revealed to the Knights?

The episode title and official synopsis point to Aiolos's last message being uncovered by the Knights, revealing his legacy and entrusting them with a sacred mission. A common plot-specific question would be about the content of that message and what it changes for the heroes.

Which Knights are sent through the Twelve Houses in this episode, and why are they the ones doing it?

According to the episode synopsis, Seiya, Shun, Shiryu, and Hyoga are the ones who must pass through the Twelve Houses after Saori is wounded. This is a character-and-plot question focused on the specific group of protagonists involved in the rescue effort.

How does this episode connect Aiolos’s legacy to the broader mission of the Bronze Knights?

The official description says Aiolos's legacy is revealed through his final message and that this message entrusts the Knights with a sacred mission. A viewer question about this would usually ask how Aiolos's words alter the Bronze Knights' immediate objective and their understanding of what they must do next.

What exactly happens when the Knights uncover Aiolos’s final message?

The episode synopsis indicates that the Knights uncover Aiolos's final message as the key event of the story, but the provided results do not spell out every scene beat of how that discovery unfolds. A plot-specific question about this moment would focus on who finds it, what form it takes, and what specific instructions or revelations it contains.

Is this family friendly?

No, it is not especially family-friendly for young children or very sensitive viewers. It's an action-fantasy episode centered on life-or-death conflict, with characters fighting for survival and confronting a powerful foe inside Sanctuary.

Potentially upsetting or objectionable elements may include: - Intense combat and sustained battle tension, including "fight for their lives" stakes. - Fantasy violence involving knights, powerful attacks, and dangerous temple-like settings. - Threatened or implied harm to major characters, including a situation where a character is struck by an arrow tied to a critical life-or-death condition. - High emotional intensity, with themes of sacrifice, urgency, and uncovering painful truths. - Mildly dark fantasy atmosphere, since the episode takes place in the House of Sagittarius and involves an unexpected enemy and survival-focused confrontation.

If you want, I can also give you a simple parent-style age suitability rating such as "OK for older kids," "teens," or "not for young children."
