1x7 - Wildfire

When Wildfire loses a big race, the Raintree team discovers that he has ingested cattle feed, which is potentially lethal for horses. Matt and Kris think it is most likely Carlos, a former Raintree employee. They later discover it is Ricky, Carlos' son, who is giving Wildfire the harmful feed. Matt is in debt from gambling, and he must sell his motorcycle (which his dad had given him) to make good. Meanwhile, Junior supports Dani when she goes to the hospital for a health issue and she later repays the kindness by reinforcing to Kris that Junior is actually a good guy. Kris and Junior re-kindle their romantic feelings for one another.
