Both Big Sky (Season 3) and the reboot series, Walker, have a character who is a charming good ol' boy from Texas (scruff and all), who happens to be in law enforcement:
And a Hoyt:
Girl Hoyt Boy Hoyt
So each time Dean Beau mentions his (yet to be seen) brother, I can't help but imagine how perfect it would be if a Sam Cordell-ish character popped up in an episode somewhere as the above-mentioned (sounds-like-trouble) brother?
