Sleet has the eyes of an eagle, perfect for scouting. He joined as the fourth wolf for the pack. When he joined, the second wolf that's in Kalani's pack left. There's a possibility it was Siberia who 'chased" them off. Not a good scene you should get when you first join a wolf pack. However, Sleet has a chill enough personality to let it slide. Thankfully he gave them a chance since he's the best scout they've had. In the beginning, he had a loner vibe to him. Soon enough he opened up to everyone after he's proved himself. He's developed somewhat of a bromance with the leader and a romance with the pack hunter Siberia.
