Sam's point of view
A loud noise yanked the Winchester out of his dream and back into reality. His sleepy eyes found Dean, standing on the other side of the bed. Dean? He must've fallen asleep. But how long? Still confused, Sam looked at Castiel. The angel was still lying motionless, but his eyes were open and looking directly at him.
"Cas?"
"Hello, Sam," Castiel said weakly. " I didn't mean to wake you." Cas was awake. "How long was I asleep?" Sam asked. "Almost two hours," Dean replied. "And you look like crap, Sammy." His older brother grinned. "Jerk." "Bitch."
"How are you feeling, Cas?" Dean asked. "I'm alright. You asked Crowley for help, didn't you?" Even though his voice was faint, the words left no room for doubt. "You don't deserve to die, Cas. And besides, there aren't many angels left," the older hunter tried to explain. "Help me out here, Sammy." "We don't even know where Crowley got the grace. It could've been stolen from another angel," Sam pointed out. "You're not helping," Dean sighed.
"That's true," came another voice. "You really don't know from where I got it." In the blink of an eye, Dean drew his gun and aimed it at the demon standing in the corner. The heart monitor started beeping wildly. Castiel sat up abruptly, ignoring the dizziness and blurred vision. Dean rushed to his side, but Cas pushed his hand away. "Hey, Cas, you need to calm down or someone will come in here," Dean warned. Castiel's eyes blazed with anger as he stared at the King of Hell. His heartbeat steadied. "What are you doing here?" Cas demanded. "I just wanted to see how my favorite angel was doing. A few hours ago, things weren't looking good for you. Dean, Dean, Dean. You know regular bullets can't hurt me. Put the gun down before I reconsider our deal."
The Devil grinned while Cas glared at him with pure hatred. Frustrated, the hunter lowered his weapon and shoved it back into his waistband. "Where did you get grace, Crowley?" Castiel asked. He tried to stay calm but his voice trembeled with fury. Sam sensed Castiel was about to lash out and gently pushed him back onto the bed. "Relax, Cas. Don't worry," Crowley said with a chuckle. "An old friend gifted it to me a long time ago. He was a loyal servant of the Lord." "I don't believe a word you say," Cas growled. "As fun as this has been with you boys, I have an important meeting. I am still the King of Hell, after all. Excuse me." With that, Crowley vanished, leaving the three of them alone in the room.
Sam and Dean exchanged a confused glance. Castiel, on the other hand, seemed completely calm. "The next time I see him…" he muttered. The brothers stared at him, surprised. His face was still neutral, but something in his expression had changed. After a moment, Sam realized what it was: Revenge. Honestly, he had never seen Cas show this much emotion before. "You sure about this? He did save your life," Dean said, breaking the silence.
Without a word, Castiel carefully removed his IV, grabbed his trench coat from the chair, and left the room. The two hunters followed him quickly. "Cas, where are you going?" Dean called after him. Cas didn't even look back.
A nearby nurse noticed the fleeing patient. "Sir, you can't just leave like that!" she called out. The angel didn't react but stood still without turning around. The nurse approached him and placed her hand on his shoulder. In an instant, Cas turned around and gently touched her forehead with two fingers. She collapsed instantly, motionless on the floor.
