Faolán had to run a little, for the climb to the mountain, closest to where they had started up, was a few kilometers away.
He found the first wolf, unconscious, on the floor. Being in animal form, he knew from afar that that werewolf wasn't dead. Whenever a werewolf dies, he reverts to his human form.
Faolán took him to the foot of the mountain and climbed back up. The other two who had fought each other, lay dead. The fourth and last was crouched in a corner, teeth chattering from the cold. When he saw Faolán, he seemed unsure whether or not to go near him. Probably thinking it was some kind of illusion. In the end, Faolán had to go to him and as they descended, the other wolf was waking up.
Mac-Tire's Alpha transformed into his big white wolf and allowed the werewolf that was weaker, in human form, to climb onto his back so they could walk.
