Jack Montgomery

Jack Montgomery is a married man who lives in Carthage, Missouri, and has the Rugaru gene in him. He begins to exhibit signs of his oncoming change, when he appetite increases. This increase later leads him to eating raw meat.

When his wife cuts her finger, the Rugaru in him want to taste her, but he overcomes this urge and leaves. He heads to a bar, and later heads back to his house. Later, Sam and Dean come to talk to him about whats happening to him. Jack doesn't believe this. They tell him he can overcome this; if not, they will have to stop him. Jack gets angry, and tells them to get off his property.

He almost gives into the Rugaru in him, until he sees his own reflect and stops. He heads back home, only to be knocked out by Travis, and wake up tied up. He also finds out his wife is pregnant. When Travis is about to burn his house down, Jack breaks free, and takes the first bite. His wife watches in horror, and runs away. Sam and Dean arrive on scene, only to be knocked out by Jack. Sam tries to help Jack one last time, but Jack is now a Rugaru. So, Sam has no choice but to burn him to death.
