Explore Torstein’s story
A dependable companion
He carries news of Rollo’s torture to the injured Ragnar and swears allegiance after Ragnar becomes earl. His role connects the household’s immediate dangers with the wider warrior group.
False death and real cost
His apparent poisoning helps mislead Horik during the Season 2 conspiracy. In the Mercian campaign he suffers a worsening arm wound, undergoes amputation and dies in battle.
The campaign seen from below
Torstein’s arc makes the expedition’s physical cost visible outside the ruling family. He is not merely evidence that a battle is serious. His continuing participation, injury and death ask what loyalty requires from the people who do the fighting while rulers negotiate the benefits. Follow the practical help he gives as closely as the blows he takes.

Memorable scenes
The apparent poisoning
Season 2, episode 10
Floki’s apparent killing of Torstein helps convince Horik that an ally is prepared to betray Ragnar. Torstein’s survival changes the meaning of what Horik thought he had witnessed.
Why this moment matters
The apparent poisoning helps Horik believe that he has correctly read Floki’s resentment. Torstein’s survival reveals how completely the conspirator has mistaken a performance for access to another person’s intentions. The scene also depends on the trust inside Ragnar’s circle: a companion becomes part of a deception intended to protect the household rather than secure a crown for himself.
The warrior who goes first
Season 3, episode 3
Despite the worsening injury that has already cost him an arm, Torstein leads the ascent toward the Mercian force and dies. His loss makes the price of the expedition visible outside the ruling family.
Why this moment matters
Torstein’s damaged body prevents the campaign from being experienced only through the ambitions of its leaders. His decision to go first is courageous, but the courage does not make the loss smaller. The scene places a trusted companion’s finite life beside the rulers’ continuing plans, asking what their victories actually demand from the people carrying them out.
Why fans keep talking
Torstein’s appeal comes from a kind of loyalty that feels practical rather than ceremonial. He brings information, shares danger and remains present through the expedition’s ordinary work. His final battle gives that steadiness a cost, which helps explain both affection for him and frustration that the original companions disappear so early. The emotional effect depends on accumulated familiarity: a smaller role can feel indispensable without being given a separate struggle for power.
What resonates
Loyalty and the grounded emotion of his last battle make him a favorite among viewers who miss the original crew.
What divides viewers
The regret surrounding his story often concerns how early those companions disappear, rather than dislike of Torstein himself.
