Dean was worried about Cas. He almost hadn't left, but the man he assumed to be Castiel's father... he didn't want to take any chances. So now he was pacing around his house, biting his nails, trying to figure out what to do. Eventually he ran up to Sam's room.

"Sam! Do you still have Gabriel's number?" He asked. Sam looked up from his book.

"Yeah, I think so, why?" He asked.

"I need it. I need to call him," Dean said. Sam must have heard the urgency in Dean's voice, because it didn't question Dean any further, he just got up and got a piece of paper from the top of the dresser.

"Here," he said, giving it to Dean. Dean grabbed it and dialed the number. It rang a few times before Gabriel picked up.

"Hello?"

"Gabriel, it's Dean-"

"Oh thank god! Dean please get over to my house. Castiel isn't texting me back, I'm really worried about him."

"I was at your house just a minute ago, Castiel and I kissed and your dad saw."

"Shit. Get over there now, Dean, please!" Gabriel hung up and Dean rushed to his room and grabbed the keys to the car.

"Dean, what's wrong?" Sam asked, following him.

"Cas isn't answering Gabriel's texts, I have to go," Dean answered.

"I'm coming with you," Sam said. Dean almost argued, but he didn't have the time. He just got into the car and drove like a madman as soon as Sam shut the door.

When they pulled into Cas' driveway, Dean jumped out of the car. He didn't have time to question why the door was unlocked, he just started running around the house, looking for Cas. Eventually he made it to the upstairs, where he found a locked door right across from what he assumed was Cas' room.

"Cas! Cas, open the door! Cas!" He yelled. No one answered. Dean rammed his body against the door, but it didn't open. He let out a scream and kicked the door, hard, right next to the lock. This time it burst open, revealing Cas, lying with his head against the tub, his eyes closed. He almost looked like he was sleeping, except for the growing stain on his shirt where his wrists rested.

"Cas!" Dean exclaimed, his voice breaking. He rushed forward and dropped to his knees, pulling Cas into his arms.

"Oh my god, Dean..." Sam was standing in the doorway, his face white and his eyes wide.

"Call 911!" Dean told him. Sam pulled out his phone and Dean looked back down at Cas. He picked up Cas' wrists to see deep cuts on each one.

"C'mon, Cas," Dean growled, tears leaking out of his eyes. He looked around and grabbed two hand towels, pressing them to Cas' wounds as best he could.

"Please... please, Cas. Don't leave. Don't leave me," Dean begged, hunching over Cas and rocking him back and forth. He could hear Sam talking, but all he could think about was Cas. Cas couldn't die. Especially not like this. He wasn't sure how long he sat there, rocking Cas back and forth, but he felt like it was forever before Cas' body was being pulled from his hands. Dean followed them to the hospital after making sure Sam could get home. Sam didn't want to leave, but Dean insisted. Gabriel met Dean in the waiting room. Dean hadn't even thought to call him, but apparently Sam had. When Gabriel saw Dean, he stopped. That was when Dean realized that he was shaking, crying, and covered in Cas' blood. Gabriel walked over, his face white.

"They still haven't told me anything," Dean said shakily. Gabriel nodded and sat down.

"I... I'm going to go get cleaned up," Dean said, before wandering off to find a bathroom. He washed the blood off his hands and tried his best to get it off his shirt, then he just stared at his reflection in the mirror. He had been trying so hard. But it wasn't hard enough. He never should've left Cas. This was his fault.

Dean wiped his face and want back out to the waiting room. When Gabriel saw him, he shook his head. No news. Dean settled into his chair to wait.

***

It was the next day before Cas woke up. Gabriel had just told Dean he was going to the bathroom. As the door swung shut, Dean pulled his chair closer to Cas' bed and took Cas' limp, pale, hand in both of his.

"I'm sorry. Oh god, I'm so sorry. I shouldn't have left you, I shouldn't... this is my fault. I... I failed you," Dean said. Tears began to trickle down his face. "I tried. I tried, Cas." Dean slipped out of the chair and onto his knees on the floor, clutching Cas' hand for dear life and breaking down into sobs. He squeezed Cas' lifeless hand. And Cas squeezed back. Dean's head shot up, and, seeing Castiel looking back at him, jumped up and pulled Cas into a tight embrace, lifting him off the bed slightly. Cas patted Dean lightly on the back. It was only when he heard the door open behind him that Dean let go.

"Castiel!" Gabriel cried, rushing forward. Dean went outside to find a doctor, smiling. Cas was awake.
