To say that Beau Clayton was a good old Southern Boy would be an understatement. The man kept a can of green boiled peanuts on his desk, for crying out loud. For some reason, it was half-filled with bullet casings.

 

I think I can see where this one is going...

 

“May I ask why you have bullet casings in that can, Sheriff?”
“Every time someone shoots at me, I put the casings into the can,” he said.

 

Yeap, lol. Beau Clayton is likely my most favorite normal badass of all badasses. The guy is surrounded by monsters and magic power-houses, and he still ends up being the solution for averting a war by sheer aplomb alone later.
