Sammy! Run!
Sam jolted awake gasping for air and pain surging through his shoulder. He took a few shaky breaths before pulling himself off the ground. His shirt drenched in sweat and blood dried above his left arm.
"Dean?" he called into the dark room. No answer.
The discomfort of the layers above the wound made it almost unbearable. Carefully he peeled his jacket and shirt off revealing the blistered and infected wound to the cold air. Sam had to look away because of the smell of burned flesh was too revolting.
He sat there a few minutes ripping his flannel shirt and wrapping the wound as well as he could before standing up. He was dizzy but it was best to leave and find Dean or Cas, but this obviously wasn't the same building they were at earlier.
As he limped down the staircase to the first floor he whispered a prayer under his breath, "Hey Castiel. I don't know where I am and if you can come get me that would be great."
Sam stopped a few seconds expecting to hear the flutter of feathers and after not hearing them concluded that Cas was preoccupied.
To be honest he was distressed about his brother and his friend. He had no idea what had happened, just a normal case of a crossroad demon, then there was a bright light. He felt Castiel grab his shoulder then he was here. It made no sense and how Castiel had managed to burn him he wasn't sure.
Sam was now out of the abandoned building. It was night but people were still wondering about, a few giving Sam strange looks. He sighed and looked around not sure what to do now. He needed a hospital and a phone but his thoughts were interrupted when someone tapped his arm.
"Hey, are you okay?"
Sam whipped around to the woman. "Um yeah, do you know where I can find a hospital?" he gestured to his arm.
"We'll get you a cab. Here you need to sit down and let me see it. I'm a doctor, don't worry."
Sam nodded and allowed her to lead him to a bench. Where she began to examine the burns. "It's really bad," she said peeling up the cloth. "How did you even get these?"
Sam winced. "I don't know. I just woke up with them."
"I'm Martha by the way," She helped Sam up and led him to the black taxi. "Martha Jones."
