The forest where he ran and hid there was very far from the capital, to get there he must take a two day walk but since he the wolves didn't eat the horses. He could use that as a mean of transportation, he should reach the castle or capital in less than a day then.
When he got out of his house with his weapons ready, he also prepared a ton of food for the trip. He leaned forward only to find the wolves sitting, and the horses laying on the ground. He untied the horses and rode one of them at their backs, the wolves stood up one by one. He just noticed that it seems like the wolves wanted to help him in his quest.
“You guys are going to help me??” he asked.
The wolf nodded in respond, it was that capable of understanding human communication. Soon after that they went on to take revenge and kill the king of the kingdom he used to live in.
