Lagertha’s (played by Katheryn Winnick) fate has been very much up in the air and fans have been desperate to find out if she will survive the second half of season five.
In a blink-and-you’ll-miss-it moment from the new trailer, Lagertha can be seen falling to the floor in her battle attire.
It looks as though Lagertha’s head has been pulled back and her throat may have been slit before she slumps forward.
Who could have ended her life?
Ivar the Boneless (Alex Andersen) is most likely her killer as he can be heard promising to murder the former leader of Kattegat.
However, it could simply be a red herring as Lagertha appears in the trailer much later several times.
She can be seen alongside Bjorn (alexander Ludwig) as they seek refuge in England as they plot to take down Ivar.
Furthermore, actress Katheryn hinted at San Diego Comic-Con that she isn’t going anywhere.
She told fans: “The very last shot of Lagertha, she is completely in shellshock – so much that her hair actually turned grey.”
Lagertha can be seen sporting her new look throughout the teaser clip hinting she will be around for sometime.
It comes after fans feared that she would be making a shock exit in the second half of season five.
The actress has been busy sharing behind-the-scenes shots of her time as a director on her Instagram page.
Her new role suggested that she would no longer be featured in front of the camera.
Furthermore, she had just landed a new role on Netflix drama Wu Assassins.
Could season five be the last fans see of Lagertha?
While the viking warrior’s fate may still be very uncertain, Rollo (Clive Standen) is very much alive.
The trailer shows him returning to Kattegat for some unfinished business.
When asked why he has come back, he simply replies: “Because I missed the old place.”
Vikings season 5 continues November 28 on History.
