Sam's stomach seemed to drop out from underneath him as Dean turned his full attention on him. His jaw tightened as he finally found himself alone with his brother in the expanse of the gym with no more time to put off what he knew was inevitable. Either it came from him or from the Insider.
"He mentioned dad," Sam said, his jaw still taught even as he said it. He might have sounded angry, but the truth was he was just trying to control his voice. He felt a wave of anger move through him that he even had to be doing this to his brother, wondering again if this had been the plan all along. "He's trying to tear us apart, Dean. He's trying to turn us against each other and I'm not going to let that happen."
His eyebrows moved together as he looked down at the gym floor. "I didn't mean to lie to you. I didn't know how to tell you. I tried to, but I just couldn't..." He trailed off before swallowing and looking back up at Dean, guilt stamped across his face. "I was trying to protect you."
His face softened into one of regret. "Dean, I'm sorry."
