Tyr, the Ragnarsson that had no family yet he had somehow become the most feared son of Ragnar. He was getting the experience even his brother and father might never have yet he was getting it at such a young age.
He was experiencing multiple fighting styles and warriors, but for some reason, he was assimilating their fighting style and making it his own.
This was an innate skill that Tyr was developing, but he could not assimilate Gissur's fighting style showing him there was a limit to what he could learn.
The night had come and Gudrun had snuck into his bed, he knew she was there but he pretended not to.
Gudrun did not try anything perverse and just laid in silence beside him, wrapping his hands around her because all she wanted was to feel his warmth but Tyr was beginning to find this to be more of a burden than comforting.
