Challenge 1: Challenge Word = Cool.
Challenge 2: Make it a dialog fic. Here's a Winchester brother squabble, settled in the usual way. Happy New Year everybody!
The usual way
"That's the end of it Sam ... I'm doing it and that's final."
"Final huh ... what gives you the right?"
"Because I'm the oldest and what I say goes."
"That's crap Dean. I'm not twelve anymore ... I'm just as capable as you are."
"Over my dead body."
"That's what I'm afraid of."
"Okay bro how 'bout we settle this the usual way?"
"Cool ... ready when you are."
"If you ask me," Bobby muttered as Sam fisted a rock whilst Dean held out scissor-fingers. "That's one helluva a way to decide who's gonna be bait for a werewolf."
