Floki actually is Loki
The show has a bit of magical realism going on, with Ragnar witnessing visions of Odin. Assuming he isn't just seeing things, that makes Loki's involvement possible. Floki is a mischievous person, and he is directly responsible for the battle between the vikings and englishmen in episode 3. He did that on purpose! Look at that face he makes after the Saxon are massacred! Floki also has a notable fascination with fire, and Loki is often identified as being the fire god in Norse Mythology
- When Rollo converts to Christianity, all the other vikings are either amused, confused, or unsure about it. Floki, however, is openly disdainful of the whole matter, spitting on the ritual and refusing to kneel when everyone else does. Possibly, as a norse god, he is offended by this new, encroaching religion.
- Alternately, he's Odin. If his smirk after Rollo slaughters the Christians to affirm his allegiance is any indication, he may have actually counted on that happening. It could be his way of using him to strike out against this new faith. Odin is also the sender of rage in battle, after all.
- Except that Odin is missing an eye. Whenever he visits Midgard, he takes the guise of a one-eyed wanderer. He's also not associated with ships in any way.
- Neither is Loki.
- Helga says Floki is always hungry, to which Floki says of "course". Remember the tale of Thor's Journey to Śtgarša-Loki? The tale where Loki almost out-eats fire?
- Gustaf Skarsgard did mention in an interview that, much in the way Ragnar believes himself to be a son of Odin, Floki believes himself to a descendant of Loki. This would make him half-brothers with a giant snake and a giant wolf.
Gyda will convert to Christianity
Bjorn will obviously follow in his father's footsteps. Depending on the show's timescale, this may result in Bjorn accompanying his parents on raids. Aethelstan, meanwhile, will stay with Gyda, and manage to convert her, assuming he doesn't lose his own faith.
- Jossed, Gyda dies of the plague.
Athelstan will lose his faith
Possibly becoming an atheist, possibly becoming a pagan. Bonus points if Ragnar goes Christian at the same time. note
- Certainly by Trial, he expresses anger at God for the first time in his life, questions his circumstances, and expresses that he feels lonely (spiritually). If nothing else by that point, he's having a severe crisis of faith.
- In Sacrifice, he takes part in the pagan festivities at Uppsala, and claims that he is no longer a Christian. However, he quickly has second thoughts about this when he learns that the only reason he was brought there was to be sacrificed. At this point, it looks like he could potentially go either way.
If the show lasts for more than a few seasons, Ragnar and friends will discover America
This sounds like something that could happen when he's exhausted other areas to explore.
- Probably not. But he may get thrown into a pit of vipers by Aella and his sons will lead an army that pillages Northumbria until they get him and torture him to death with the Blood Eagle.
- Now that a second season has been confirmed, Clive Standen (Rollo) has said that we may see many well-known figures from that time period, including Leif Ericson. If that turns out to be the case, then a journey to North America may not be out of the picture.
Rollo will become an Olfhednar
He already displays berserker-like tendencies and is devoted to Odin as a war-god. I know he's supposed to end up ruler of Normandy and convert to Christianity, but this series already takes liberties with history so this could happen.
- Well, so far he has become christian, though he himself claims he wasn't serious about it.
Lagertha didn't miscarry
Rather, the baby was born, but due to complications, his legs will be crippled or otherwise deformed. The child will grow up to be the show's version of Ivar the Boneless.
- Jossed. Sacrifice shows that it was indeed a miscarriage. But it does seem likely that Aslaug will bear those children.
Ragnar will take Aslaug as his next wife, and all sons he has from hence will be from her.
She's confirmed to be in the next episode and will be a recurring character in season 2. I think it's obvious. She was one of his wives in the sagas.
- Yep, she's already pregnant with their first child.
The series finale will show Ragnar's death
The final scene will have an adult Bjorn leading the Great Heathen Army against England.
- Why stop there? Show Bjorn, Hvitserk, Ubbe, Sigurd, etc taking down Aella. And show them doing the Blood Eagle, too.
- You know, this isn't really that wild a guess. Anyone whose read the saga (and it has been around for maybe 7 or 8 centuries) already knows that it ends with Ragnar's death and his sons avenging him.
That wanderer who gave Ragnar the sunboard and icelandic spear was actually Odin
He knows (he knows everything, he's Odin) that Ragnar is in for a life of blood and battle and this pleased him. So he decided to jolt things along and give Ragnar all he needed to start his legend.
Floki and Athelstan will become close friends because of their shared spiritual natures
They'll still come into debates about their differing religions, but they'll respect each others beliefs and ways. Certainly both seem like the type to respect devotion.
All but confirmed, if this interview with Michael Hirst is anything to go by
This troper really, really
hopes that Alfred is portrayed sympathetically. The real guy was pretty awesome (just take a look at his page on this wiki), and it would be a shame if they tried to make him out to be a more capable version of Aelle.
- Alfred the Great technically became notable after Ragnar's death, but they've changed the dates so Ragnar lived in 793, so it's all good. And this show basically grew from a personal project Michael Hirst always wanted to do depicting Alfred the Great. Anyway, no need to worry about Alfred's portrayal - Aella is portrayed as an asshole because that's how he is in the Anglo-Saxon Chronicle. The real challenge is gonna be in portraying Alfred so that he doesn't come off as a Mary Sue.
- Though, in all likelihood, it'll probably be Ecgberht of Wessex.
- Yep, Linus Roache will be Ecberht.
- Huh. Bjorn's being played by a different actor too. Seems like there'll be a timeskip.
Magnus Samuelsson will have a role
Why not? They already got Jauko Ahola.
Earl Haraldson's name is Harald
His father was already called Earl Harald, so they called him Earl Haraldson when he succeeded to differentiate between the two.
