Adrenaline begins to pump through his veins with every step. His heart was racing more than it should be. Perhaps it was the storm or this mare that was stirring such a reaction. It might be the way her body reacts to him. At first she races forward to give him a challenge. He assumes she was enjoying the chase up until he nips at her haunch. Still, she doesn't seem too upset by the action. She does react to which he tries his best to stay in the race.
Warwick was not made for speed. Sure he enjoyed a chase now and again, but fighting was his true passion. Strength was his best quality, that and his hardy body surviving the elements. So as her shoulder drives into his he has to immediately slow down and shift angles. He tries to pick up speed again, pulling back again to avoid her joyous buck. She was absolutely having fun. This causes him to chuckle even though he felt himself getting slower and slower.
It was his wish to keep going, but the travel had taken a lot of his energy. This might be a good thing for her so that he was more calm for their first meeting. He laughs at the thought as he finally stops. The rain begins to trickle around him before quickly becoming a downpour that sticks his thick mane to his neck and his face. He nickers loudly to her thinking maybe she would turn around and join him.
After all, he had no plans of letting her slip away so easily.
