Every soldier in the pack sprinted to the ambush area in formation. Some were left behind to protect the headquarters, but Rhett had a bigger priority.
Isleen and Kylo wouldn't have gotten home before this. They lost and certainly would have been caught in the ambush. So, he solo ran there on his slaying every vampire that got in his way.
He could already see Kylo in his wolf form, fighting off vampires and biting into them before they could get him. That was his son, he smiled.
Kylo did inherit his ferociousness on the battlefield. Had he not been so protective of Kylo, he would have enrolled him in the pack's military. Kylo always fought like he was meant for it.
He was injuring and bringing down as many vampires as he could with his claws and fangs, his wolf heaving and imposing. It was only a shame that unless they cut off the vampires' heads, they wouldn't have an upper hand over them.
