What happens when Rufe Jones attacks Silas?

Rufe Jones attacks Silas. As they are fighting, Pony rears up in front of Rufe squealing like mad. He pummels Rufe Jones with his hooves as he roars with his mouth frothing. Rufe tries to protect his face, but Pony's hooves are like 100-pound mallets. Pony only stops the attack when Deputy Beautyman hits Rufe Jones in the head.
