Sam struggled to help the newly exorcised man to his feet, Ruby following behind them. And then the door opened...
And in walked Dean. Sam froze mid stride in shock.
"So. Anything you want to tell me Sam?"
"Dean, no, hold on just let me say som-"
"Let me explain? ...You're gonna explain this? In that case why don't you start with who she is. And what the hell is she doing here?"
Dean looked across at the brunette Ruby.
"Good to see you again Dean," she smiled.
"Ruby?" he looked to Sam, "is that Ruby?"
Sam couldn't respond. At the silent consent, Dean lunged for Ruby, pinning her against the wall. Sh made to fight back, but then Dean pulled her knife -
Sam intervened, pulling the knife away from his brother an splitting the two.
Ruby in turn grabbed Dean ad pinned him where she'd been seconds earlier.
"Ruby! Stop it!" Sam demanded.
Ruby hesitated, then released Dean's throat and stepped back.
Dean glanced at Sam, then returned his anger to her.
"Well aren't you an obedient little bitch?"
Ruby was about to have another go at him when Sam spoke up.
"Ruby? Ruby. He's hurt," he indicated their victim, "go."
Ruby paused, then turned to go help the man.
"Where do you think you're going?" Dean demanded.
"Back yard. Unless you want to go another round first."
After another look from Sam, she headed out. Then Dean turned to his brother.
"Dean..."
Dean walked out.
"Dean!" Sam called after him, but to no avail.
