I do not own Supernatural…However; it is very tempting to steal it…
This is set in Season 5, Episode 13; 'The Song Remains The Same' where Castiel has just transported Sam and Dean back in time.
Motel Blues:
Having left Sam to go and look up their parent's address in the nearest phone book, Dean took hold of Castiel and half carried, half dragged him into the motel and up the stairs to their allocated room.
Castiel did not look good and was spitting blood all over Dean who was glad when they finally reached their destination. The room was shabby, but not as bad as some of the places that the lads had been staying in.
'You're gonna rest it out here, Cas,' said Dean, throwing him on the bed and making for the window to pull the curtains across, 'just a few days right?'
There was a groan from the direction of the bed and as Dean turned around he realised that Castiel was lying on one side in a rather crumpled heap. Thinking that it would not be very comfortable for him, Dean pulled Cas backwards onto the pillows and attempted to straighten out the angel's trench coat beneath him. It was a failed attempt.
'Right, that'll do for now,' said Dean, heading backwards for the door, 'we'll be back when this is all sorted out and you've got your wings working again. I guess you weren't kidding when you said it would be hard?'
He paused, waiting for a response from his seemingly asleep companion. When none came he turned and reached for the door handle.
'Dean.'
Castiel's voice was quiet but pleading, it was a voice that Dean was very used to when his friend was feeling vulnerable.
'Cas, man, I thought you were out,' He started with a grin, turning back around to see a sorrowful state of a man before him.
'Dean, please.'
Dean's face fell, Castiel looked so weak and hurt that he couldn't stop himself from moving forward and sitting on the edge of the bed next to him, 'You know I can't stay.' He muttered.
'I don't want you to go,' Castiel continued, using all of his strength with each syllable. 'Stay.'
Castiel passed out and Dean reached for his unconscious hand.
He sat there a few minutes, clutching at the part he had become so used to holding when it had life in it, wishing that Castiel could be awake enough to run that hand through Dean's hair and pull him closer.
Thinking of Sam waiting outside, Dean mumbled his goodbyes and placed a delicate kiss on the sleeping angel's forehead, kissed his hand and then walked away, firmly closing the motel door behind him, an act that always kept their secrets hidden.
