Sam's scream was deafening, and Dean snapped his head over to where the voice had come from, but Dean couldn't see Sammy. There was just a man in a white coat standing next to someone lying on a bed... someone with Sammy's shoes.
Dean harshly twisted his head and bit into the arm of one of his captors. When he felt the man let go of him, Dean stomped on the foot of the doctor who had been holding onto his other arm and managed to free himself.
Cas was watching Dean's movement across the ER, but could sense that Sam was now starting to cry; the boy had begun trembling as soon as he had heard his big brother's voice calling for him.
Dean began sprinting towards Cas, with the cop right on his heels, and Cas knew he needed to make a decision quickly about how to handle this unique situation.
Seeing Dean running at full force, Cas let the kid come right at him, and just as Dean made it to Sam's bedside, Cas used the boy's momentum to lift him up onto the bed behind Sam's head.
The police officer stopped in the doorframe. "Dr. Castiel, this boy needs to come with us. He robbed a convenience store and-"
"No," Cas found himself saying more forcefully than he had intended. "After seeing the condition of the brother, I can only assume... he needs medical attention. They... they need to stay together."
The police officer didn't back down, so Cas gestured with his head for him to come look at Sam's torso.
When Cas turned back to look at the boys, his breath halted. This older brother, Dean, was now a completely different person than the one who had just assaulted the two men moments ago.
Dean sat calmly right next to his brother's head, soothingly stroking his hair and holding his hand. When the cop saw the bruising on Sam, and the way that Sam reacted to the "thief", he nodded to Cas. "I'll be back in a few hours," he said softly.
Cas shut the curtain around them after the cop left the small exam room. He turned towards the bed and Dean locked eyes with him. Cas was startled by the amount of fear the boy's eyes possessed.
"Is that better, Sam?" Cas asked gently, somewhat ignoring Dean's added presence. "Now that your superhero is here?" Cas hoped Dean would get the point Sam had already started opening up to him and trusting him.
"Yeah, Cas," Sam whispered up to Dean, who had leaned forward so that Sammy could see his face. "It's better now."
Dean looked defensively over to Cas. "Were you hurting him? Why is his shirt off? How did he get here?"
"Dean, someone found him in the alley... by himself. They called an ambulance that brought him here and I've been taking care of him to see how I can help." Cas chose his words carefully. "His arm is hurt and I cut off the shirt so I could examine it better-"
"He's a good guy, Dean," Sammy said up to his brother, still lying flat on his back. "He's gonna help your head."
"Sammy! No!" Dean whispered harshly.
"He told me about what happened tonight, Dean. That you hurt your head... and I will help you too, later, but first I need you to be my assistant a bit to help me take care of Sam. Can you do that for me?" Cas saw how protective Dean was and thought maybe he could use Dean to help him treat Sam.
Dean looked down at Sammy and nodded. "Ok. I can help," he said with a tremor in his voice, "but you're not allowed to hurt him."
Cas raised his hands up with his palms facing out towards the boys and smiled. "I promise. I won't hurt you. Either of you. Can you trust me?"
"Do you want him to fix your arm, Sammy?" Dean asked down shyly.
Cas couldn't hear Sam's reply, but he felt relieved when Dean looked up at him and said, "Ok. You can fix him."
