What happened to him? He was blinded by rage. He just kept running and charging. Going after one target, the one thing he saw when he went into this rage. Tav. They were running from him, not wanting to hurt him.

He warned them he wouldn't be able to control his form if he changed but Tav didn't listen. They were instant on having his help with this fight. Which, they won the fight but at what cost?

Now they had a fully grown bear chasing them.
