Great casefic, nicely paced tension, with bonus badass boys!
I like all your characters, Sarah and her last requests list while Sam kipes the gun.
And Billy the kid-who so needs to be smacked. John deserves a halo.
Wish Sam could have heard John describing his "man on the inside"!
And the sudden realization when Sam and Dean figure out they're both safe "we gotta stop Dad!"
Loved it!
