Does anyone have any almost for sure proof that Kris and Junior get married on Wildfire?

Ok, I know this is Wildfire's last season, and Kris and Junior will most likely get married. But I need to know for sure. Can anyone point me in a direction were I can find proof or something that it REALLY happens. Iv'e seen the promo's, but if there's anything else, it would be amazing if anyone could let me know!
