It's a battle between Ragnar and Rollo, each with their armies.
Blood is spilled and lives are lost. One of those lives, sadly, is One Eye. He was viciously speared by Rollo, who didn't seem to show any remorse until after the fact.
That's when Ragnar steps up to challenge his brother.
Though he had no trouble joining up with Jarl Borg, Rollo threw down his weapon in the face of Ragnar. He couldn't attack his own brother.
King Horik and Borg were able to reach a compromise, with a plan to raid the west together, building a better life for both sides. Rollo was taken into custody.
Once back home, the townspeople expected Rollo to be killed for his betrayal, but he was spared.
Ragnar's son Bjorn informs Lagertha of his indiscretions with Princess Aslaug at the end of Season 1, leaving her far less than happy.
She makes Ragnar promise to never see his mistress again, which he readily accepts.
Everything changes when Aslaug appears at Ragnar's home, pregnant.
Ragnar tries to sell Lagertha on letting him have them both as wives.
Ragnar is surprised to learn that Lagertha has left him. After chasing her down, he realizes he's lost his chance.
Unfortunately that also gives Bjorn a chance to reconsider leaving with his mom, which he chooses to do.
Now, Ragnar's family has left him, and a pregnant Aslaug is waiting for him at home.
