I am honestly intrigued by this character. I have a few ideas that I can send over, but a super quick one that has me thinking is listed below.

Supernatural Idea
Ranch has been used in agreement with the US Marshals as a safehouse for transferring people in witness protection. Unbenounced to them the otherworldly hunting the family does has started to gain attention so now not just criminal elements, but supernatural elements are converging on the town and ranch just as the Marshals arrive with another witness transfer.
