The season finale of 'Vikings' concluded with a bang and Bjorn Ironside (Alexander Ludwig) is finally the king of Kattegat. As applaudable the episode 'Ragnarok' was, there were few loopholes that we chose to oversee, such as Lagertha (Katheryn Winnick) and Ubbe (Jordan Patrick Smith) returning to Kattegat right after Bjorn is proclaimed the King.
Okay, let's just address that, Lagertha knew Ivar sat on her former throne and she chose to return "home" from Wessex with Ubbe, knowing full well Ivar thirsts to kill her. What if Bjorn had failed? Had it not been for Freydis' ultimate betrayal, Bjorn and Hvitserk wouldn't have a chance against the ruthless Ivar.
The conclusion was also a blur. After Lagertha presents Bjorn with a sword, he gets transported to a dream-like haze. The cheering crowds behind him turn into bloody corpses, the shiny silver sword suddenly is stained with blood and then, again, he is perched on Ragnar's spot, at the hilltop of Kattegat, and the Seer, who is already dead, appears to make another prophecy; the war is not over yet. Bjorn questions if all of this is real, he can't tell and neither can we.
The trailer for season 6 came out shortly after the finale aired, and while we got a fair idea about what to expect, here are some burning questions we have about season 5B's finale. Will the last installment answer all these burning questions? Let's just put this forward for now.
1. Is Floki dead or alive?

The last we saw of the boat-builder was in the penultimate episode where, after abandoning all his human followers, he went to explore the cave in "god's land." His arduous long journey, spiritual and physical, came to a shocking conclusion when the Christian-hating 'Viking' discovered a cross inside the cave. No Thor, no Odin, no Freyr. Frustrated with the sight, he screamed in agony, making the boulders fall off the cave.
However, the scene did not show if he lived or died, but the magnitude of the rocks falling was not very lethal. The finale showed no sight of Floki, so, of course, we are going to question his whereabouts. If he made it out, where is he? If not, why did the show waste so much time focusing on his boring Icelandic ventures? There's nothing here, but questions and complaints.
2. Was the dead Seer's prophecy real?

As mentioned earlier, we could not make out if Bjorn's visions were a dream or a reality, but the Seer was reprised for another groundbreaking prophecy. While wondering if there were any truth to it, a season 6 trailer came out to answer that yup, the Seer is right. Ivar is raising an army to crush Bjorn in Rus, or so it looked, if so, a bigger war is definitely coming. This question may have been answered, but that again lead to hundreds of other questions. However, we'll stick to the finale here.
3. Will Ubbe and Hvitserk reconcile?

It was disheartening to see Ubbe rub a cold shoulder to Hvitserk during Bjorn's victory celebration. Ubbe still hasn't forgiven Hvitserk for jumping ship with Ivar, and the question is if he ever will?
4. Is King Harald alive?
Hopefully, he is, since his wound did not deter him from standing and even fighting. But his absence at Bjorn's coronation makes us rather concerned.
5. Is Gunnhild pregnant?
No signs of it yet, but Gunnhild boldly tells Bjorn she wants to have sex after their initial defeat, prior to their victory. "Listen, I want to have sex. I might die tomorrow. Or you might die tomorrow. But in any case, if possible, I should like to be with child." Bjorn already has children with Torvi, and he knows he hasn't been the best father, but sure, he loves Gunnhild, so, why not?
6. How did Ivar escape?

After killing Freydis for her betrayal, Ivar goes missing from the hall of Kattegat. When Bjorn and Hvitserk enter the hall after the last fight, Ivar is nowhere to be found and Freydis' dead body is on the bed. Ivar, as a "cripple," surely could not have dragged the dead body and placed it on the bed all by himself, especially given how little time he had to escape.
Did somebody help him escape? If yes, who could it be? At the end of the episode, we saw him on a cart, wearing a straw hat and headed somewhere, thank god for the season 6 trailer, we think he is headed to Rus.
7. Is Lagertha a follower of Buddhism?

Hvitserk abandoned his Buddha idol prior to the Kattegat war, but Lagertha echoed the principles of the Buddha when she tells Torvi that life is all about suffering. "How do I tell my children life is all about suffering?" Torvi asks. "They will find out for themselves," Lagertha quips. "What’s important is how we deal with suffering, how we deal with the truth."
Despite citing she wants to go back to being a farmer and attaining the happiness she once had, the season 6 trailer demonstrates she will take upon the role of shieldmaiden again and raise a band of warriors for Bjorn's Kattegat. That is why you will not find an eighth question, which would have been about Lagertha's future. Now, we know we will not be missing our shieldmaiden in action.
