Willow then asked him excitedly through their telepathic link, 'Are you going to use your Divine Wolf form to track them down, Dad?'
Axel nodded, he would be much more efficient if he used his wolf form, and as his father just reminded him, they will need to move fast.
Willow then let out one of her melodious sound to show them that she was really happy and eager to go hunt with them, and Axel then handed over Willow to Kevin before kissing them both and shapeshift into his Divine Wolf form but he of course reduced his size so that he could move more freely wherever they would go.
Axel wasn't worried that his Dad and Colin couldn't keep up with him, and so, once Kevin was settled on his back, holding Willow in his arm, he opened his senses to the maximum and as soon as he had spotted the energy signatures of Werewolves he rushed towards them because from this distance he couldn't detect if their souls were corrupted.
