Dean sat next to the bed Castiel laid on. He just got back to the room from 1978 and immediatly passed out. Sam had gone to get food and Dean kept a silent vigil on Cas. It had been about an hour and a half and Cas was still unconscious. Dean was worried. Ever since Cas had rebelled and started helping Dean, Dean thought of him as another brother. Dean was so lost in thought, that he jumped slightly when Castiel moaned. Dean got up and sat on the bed, putting a hand on Cas' shoulder.
"Cas? Cas, can you hear me?" Dean asked.
Cas slowly opened his eyes.
"Dean?" he asked weakly.
"Yeah its me," Dean answered, "you alright?"
"I believe so. I'm not in much pain as I was before," Cas whispered slowly sitting up.
He wavered for a minute and would have fallen forward if Dean didn't catch him.
"Whoa. Whoa. Take it easy, take it easy," Dean insturcted putting a hand on Castiel chest and another across his shoulders, "you should lay back down."
"I'm fine and I should go," Cas stated.
Before Dean could stop him, he got up and took a few steps. A wave of dizziness took over Cas and his knees buckled. Dean caught him and lowered them both to the ground.
"Your not fine," Dean stated.
"I just got dizzy thats..." Cas was cut short by a coughing fit.
Dean held Cas up a bit as a little bit of blood came out of Cas' mouth.
"Dammit," Dean muttered.
As soon as the coughing fit subsided, Dean got Castiel up and laid him back down on the bed. He went into the bathroom and came back with a wet wash cloth. He gently began to clean off the blood from Cas' mouth.
"I should go. I do not with to intrude," Cas whispered.
"Your not going anywhere. Your still weak and you need to rest. Which means your staying right here," Dean stated.
Cas sighed in defeat.
"Fine," he mumbled.
"Good, now lets get this coat off you," Dean told him.
Dean helped Cas get his trenchcoat off and settled in for a long night of watching Cas sleep.
