Kolbeinn was dazed, he had suffered a concussion.
He had managed to match the Mad Hound's strength for a short while before he grabbed him.
But Kolbeinn realized the Mad Hound was not even fighting at full strength during their exchange.
But Tyr had saved them, by possibly sacrificing himself but this did a number on the troop's morale.
They started to look at Tyr as a martyr, a man that would even give his life to protect them, but they also began to question Kolbeinn because he did not offer himself for their sake but then again, he was the Chieftain.
Kolbeinn's life held more weight than theirs because he was the head, but these were intrusive thoughts brought forth from the situation.
If they truly felt this way or not was up for debate.
Gudrun had rejoined with them but she saw Tyr was nowhere to be seen, Nora followed behind her and noted the same thing.
