Back at the motel was... awkward to say the least. Cas was a little freaked out by his reactions earlier and was taking a shower to help calm himself down. It was one of his new pleasures, cleansing himself in the warm water spray, letting it wash over him. Dean had gone back to sleep so Cas wasn't too concerned that he hadn't brought clothes with him into the bathroom. There was a dull ache in his back and he rolled his shoulders to try to relieve it.
That was when he heard the soul splitting rip and felt a searing pain flood through his back. He was vaguely aware that someone was screaming.
Dean was having a fantastic dream, that he really didn't want to get out that he was having. He was snuggled into Cas' arms, just laying there, reveling in Cas' warmth and security. It was safe, and it felt nice to be wrapped up in his comforting embrace. He heard a scream pierce through his thoughts and he shot out of bed.
Dean frantically looked around, going into hunter mode instantly. He noticed that Cas was gone and he panicked. "He was just here!" his brain supplied for him and it took him a few seconds to come down. He ran to the bathroom, remembering that yes, he is still here, he just went to go take a shower. What he wasn't expecting to see was a bloodied Cas huddled in the corner of the shower, rocking back and forth. He was mumbling something under his breath and Dean could see that he wasn't all there.
Dean slowly inched into the room and carefully turned off the shower before climbing in next to him. "Cas?" he whispered hesitantly reaching his hand out to touch his shoulder. "Cas, can you hear me?" Castiel's eyes looked around the shower until they found Dean's and Dean smiled. "There you are, angel..." Cas was obviously in shock. His eyes were wide and his breathing was erratic. He didn't say anything, just scooted closer to Dean and wrapped his arms around his neck, indicating that he wanted to be picked up.
"Hold on, Cas. Easy goin'." Dean said as he slowly stood up next to him. Cas shakily stood up and looked around him some more before relaxing a tiny bit into Dean's arms. Dean smiled at this and carefully climbed out of the shower, wrapping his arm around his waist. "You're going to be alright, okay? You're fine." He was moving Cas back to the bed and he laid him down on his stomach.
His back looked terrible. There was blood everywhere, dripping down his back from a gaping wound by his shoulders. It was trying to clot, but everytime Cas moved, he sent another whimper into the air and it opened the hole yet again. Dean knew he had to do something, anything but he couldn't think straight. He was pacing now, hands in his hair. After a while, a thought finally occurred to him and he ripped apart their duffle bag trying to find the medical kit, only to find that it was hardly sufficient.
Dean was vaguely aware that his face was wet, and he didn't honestly care at the moment. He went back over to Cas and kissed his head, trying to make him as comfortable as possible. "You're okay... You're going to be okay..." He wasn't sure who he was reassuring, Cas or himself. Somewhere in there he had resorted to begging and at that point, Gabe popped in, unceremoniously dropping Sam on the other motel bed.
"Gabriel..." Dean whispered quietly looking up from Cas. "Wha-"
"I heard him scream." He said solemnly and he started work on his baby brother.
