Starts from the end of ep. 11 so if you haven't seen it SPOILER ALERT if you have seen it then awesome! And I know this isn't in order but I need this so bad
Cas's body spasmed as Rowena released the spell that had been plaguing the Angel for so long. Dean watched, although he didn't look it, with pain as Cas fell to the floor.
"Do I need to remind you that these are witch killing bullets?!" Sam yelled "Finish the spell!"
"Yes, all right" she purred with exasperation coloring her Irish accent. Speaking some latin gibberish Cas's body stilled and Dean dropped to the floor to Cas's side.
"Cas?" He grabbed the side of Cas's pale face. Slowly, blue eyes opened to reveal tired but spell-less eyes. "Cmon" Dean said as he helped up the dazed angel putting his hands on either side of his neck to stabilize Cas. Cas simply stared at Dean wearily, and leans ever so slightly into his touch. The moment of peace was broken by some shouted Latin and a 6'4" body flying off into a stack of crates. Dean sprang from the Angels side as he rushed towards Rowena, unfortunately it was too late as the metal security grating slammed to the ground trapping the three inside the warehouse.
"I'm sure you had every intention of honoring our agreement." Rowena said amiably before her voice hardened "But why take chances?" She turned on her heel and walked away, deans eyes following her every move.
When the outside door slammed shut he rushed to Sam. Other than being dazed and a bit bruised from Rowena's spell he was all right. He stood up and walked with Dean over to Cas's prone form. Even though Cas had his grace back fighting the spell for over a week had been hard even for an angel. He had passed out on the cold brick floor and, rather than wake him, Dean simply picked up Cas under his legs and shoulders and carried him out to the car. Sam grinned as he saw Dean take care of Cas as he laid him in the backseat and winced in pain at the injuries he had sustained from Cas's mad dog fever.
"Let's blow this place Sammy" Dean said as the doors creaked open and the impala a engine came to life with a growl.

Dean sat at the main table just inside the bunkers entrance with an ice pack glued to his face. Sam was explaining about the darkness and finding amara when Dean took off the pack and winced as he took a swig of beer. Cas looked at the hunter with guilt in his eyes and he stood up to lean across the table "Dean please. Let me-" he held out two fingers to heal deans face but Dean blocked aside fingers with his hand."No. Cas it's fine"
"Dean... There aren't words"
"No. There aren't because you don't need to say anything" he began "besides I had it coming for me anyways" he gave Cas a meaningful look about the time when Dean, crazed with the Mark of Cain, had almost killed the Angel.
Sighing Cas sat back down and Sam decided to let them hash it out. He muttered excuses about looking for a clue in one of the more obscure rooms in the bunker and disappeared into one of the halls patting himself on the back. He was such a good brother.
Meanwhile at the table an awkward silence reigned between Cas and Dean. "Dean what you did.. It was the Mark, not you. There isn't anything you did that requires this as some sort of perverse justice"
"Cas I could've killed you, besides you weren't in your right mind either! That evil bitch had you under one helluva spell" he gave Cas an "I know I'm right" face and Cas just shook his head.
"I wish I could just protect you instead of hurt you" he spoke quietly. Dean stood and walked around to Cas's side. He placed his hand on the shoulder of Cas's trench coat and looked down.
"Maybe we just need to keep a closer eye on each other" he smiled and patted Cas's shoulder one more time before he wandered off, both with stupid smiles gracing their faces.
