*Season 4*
Sam's jaw was tight, his anger radiating across the car. He was so good at telegraphing his displeasure without saying a damned word.
Dean rolled his shoulder, preparing for a fight. "What's with the resting bitchface?"
The muscle in Sam's jaw jumped. "You and Bobby can't even pause to consider my point of view in this."
"Thats because your point of view in this is freaking crazy, Sam!" Dean exploded back.
"Is it?" Sam cheated his body toward his brother. "Is it really?"
"Yes!" Dean slammed his hand against the steering wheel for emphasis.
"What is the downside to killing demons with my mind? Huh? It's already saved our lives. It's saved a lot of lives."
Dean scowled. Didn't answer.
"When it comes down to it, you just don't trust me... After all this goddamn time you and Bobby don't trust me!"
"Yeah because you're lying and working with demons."
Sam bit his lip, the rage he had always surpressed lingering so near the surface these days. "I'm fighting a war, Dean. A war. You're running on emotion and I'm doing what makes sense tactically."
Dean shook his head, his righteous indignation building. "You're selling your soul!"
"I'm not the one who did that." Sam retorted quietly.
The air left his lungs and Dean clenched his fist tightly against the steering wheel. "Low blow, brother."
Sam turned away, the muscle in his jaw jumped as he ground his teeth. Tactically, there was nothing more to say.
