Vikings' first season saw Ragnar (Travis Fimmel) claw his way up from farmer to Earl, but the History Channel series was only getting started. "I'm amazed by Season 2. So much happens and it moves at such a pace. It's like blink and you'll miss it," Clive Standen, who plays Ragnar's brother Rollo, tells TVGuide.com.
When Vikings returns Thursday (10/9c), Ragnar will find everything he's worked for threatened by his brother's betrayal, new enemies in England and even his own ego. Standen and Katheryn Winnick, who plays Lagertha, break down exactly what viewers can expect from Vikings' anticipated second season.
