*WARNING: Spoilers ahead for Britannia season 3*

Since it arrived on our screens in 2018, Sky’s Britannia has been a must-watch for fans of historical drama with that added hint of fantasy.

In 2021, Britannia returned for its long-awaited third season and the new instalment leans further in the direction of magic and fantasy as the prospect of rebellion against the Romans grows.

However, as the episodes are packed with visions, possessions and a mystical spear, the ending of Britannia season 3 has left fans with more than a few questions and needs to be explained.

Britannia season 3 release date and plot

Season 3 of Britannia arrived on Sky Atlantic on August 24th and has been available to stream in full on-demand and via Now.

The new season sees the relationship between the Celtic tribes and Roman invaders worsen further as Aulus is joined on the scene by his wife, the bewitching Hemple.

Cait learns that the Britannic tribes could be united if she can find the sacred Spear of the Silver Dawn, the same spear that pierced Jesus during the crucifixion.

The only trouble is, its location is a closely guarded secret, only known by Lucius.

To complicate matters further, Cait learns that there is a traitor lurking in the midst of her allies.

Britannia season 3 ending explained

Fast-forwarding to episode 8, Cait is still searching for Lucius and his knowledge of the spear and she is joined by Ania, who is under the influence of a hex, placed upon her by Hemple.

Meanwhile, Divis, Rayne and Phelan are captured by a group of druids for trespassing on their land and are forced into proving their status as druids, which results in Divis experiencing a vision, showing Aulus taking Cait.

However, it’s not Ania who gives up Cait as Hemple’s hex on Ania is broken when Cait fights back against the demon, Lokka.

Cait then experiences a vision of her own where she hears the voices of Islene and Veran that tell her that the legions of the dead are with her, potentially her first step on the path to uniting the Celtic tribes.

This sets up season 3’s dramatic climax as Cait returns to the Roman camp, with Queen Antedia troops for support, as she goes in search of Lucius and his knowledge of the spear.

And while Cait succeeds and Lucius whispers what he knows in her ear, we don’t get to hear what he says.

Cait’s timing couldn’t have been better as seconds later, she’s joined by Hemple who kills Lucius and wounds Cait.

Thankfully, Cait is rescued by Divis and the gang who quickly get her out of the camp and to safety. But not for long.

It is now that we learn the identity of the prophecised traitor, it’s Divis himself, who was under the influence of Hemple after Ania had tied some of the mystical red string around his toe in an earlier episode.

It turns out that the vision Divis experienced earlier in the episode, of Aulus taking Cait, was actually thanks to him as he was the one to give her up.

How the ending set up season 4

One thing we’ve not yet touched upon is the very last scene in episode 8 that sees Cait join Aulus in Rome, offering up a jaw-dropping cliffhanger to end the season.

The ending in Rome and the dangling plot threads left in episode 8, such as the spear, hint that there is room for a fourth season if Britannia is indeed renewed.

Britannia could even be a minor feature in season 4 if Cait and Aulus were to stay in Rome.

Fans have quickly begun to speculate about the final scene, with some suggesting that Cait could be an architect of Rome’s downfall from the inside by helping to influence the rise of Christianity with the spear.

Others, however, have speculated that the scene in Rome is actually a vision or a dream, potentially showing what might happen if Cait cannot unite the tribes and defeat Aulus and the Roman invaders.
