Vikings: Hidden Ragnar Easter egg 'no one noticed' in season two revealed by showrunner

Fans were also treated to some behind-the-scenes insight, including some hidden details hidden in the scripts of season two.

Hirst, who has written every episode of Vikings so far, let viewers in on his writing process for the second season’s finale, The Lord’s Prayer.

The showrunner revealed how a suggestion from Fimmel ended up playing a pivotal role in episode ten’s dialogue.

He explained: “Travis said to me, ‘do you think, perhaps it would be a good idea if I don’t say anything in this episode except the Lord’s Prayer?’
