Dean kicked open the glass doors with a pant, running inside, holding Castiel in his arms. The blood on his stomach just kept coming, it wouldn't stop! Dean looked into Castiel's eyes, the were fuzzy and almost completely closed.
"Come one Cass, stay with me here bud." He begged. A whimper from him was a reply. A lady veterinarian ran up to them, a worried expression on her face.
"What happened?" She asked, looking at the wond on Castiel's stomach that was still oozing out blood.
"I was attacked, he tried to protect me." The Winchester quickly explained.
'Dean.' Castiel spoke to him through his mind. He sounded hurt, scared, and in pain. His voice sound strained. His black wings were pressed to his back, tightly against his grey fur, whining.
"We're going to have to get him to an E.R." The woman said, taking Castiel from Dean. "Stay here for further questions." She added. The lady wore her brown hair in a ponytail and had teal eyes. She wore the normal vet clothing, along with a name tag Dean didn't care to pay any attention to, only worrying about his angel.
"Cass!" Dean called out to him before he was gone, away from his sight.
