Castiel's Point of View

It was quiet in the bunker of the Men of Letters. The only sound was the soft rustling of turning pages. The trio had been holed up in the library for weeks, scouring every book they could find. Dean groaned in frustration and slammed another book shut. The loud noise startled Sam and Castiel. For a brief moment, tiny black dots danced in the angel's vision.

They had been searching for weeks for a way to track down Metatron. Since he was still in possession of Castiel's grace, it was essential to find him as quickly as possible. Sam and Dean had both noticed that their friend was getting weaker day by day. Charlie had created a search algorithm for them that scanned the internet for clues as to the whereabouts of God's scribe. Meanwhile, the three of them continued their manual research, though so far without success.

Suddenly, the room began to spin. Castiel felt the fever that had been lingering for days surge up again. He was cold. The pounding headaches that he had already repressed became present again. To keep from collapsing, he gripped the table. Sam, seated nearby, looked at him confused but said nothing. "You found anything?" the older one asked, having also noticed something was off.

The angel looked at both brothers with a blank, intense stare. A few uncomfortable seconds of silence passed. "No," He turned back to the old book titled God and His Servants. Then came a sudden coughing fit. "You okay?" Sam asked with concern, starting to rise from his seat. He was determined not to let them find out how bad things really were. "Yes," he managed to force out between coughs.

His vision blurred again. A hand touched his forehead. "You're burning up," Sam said, shocked. "Why didn't you say anything?" "How long have you been feeling like this?" Dean jumped in. "A few days now. I didn't want you to worry," Castiel replied weakly. His voice was noticeably lower and softer, something neither of the Winchesters missed. They exchanged visibly worried glances. Once again, the room started spinning for him. He heard someone calling his name, but he no longer had the strength to respond. The last thing the angel perceived was the floor coming toward him.

Sam and Dean's point of view

Both hunters dropped to their knees next to him, visibly more concerned now. "He needs a hospital. With that fever, he could double as a furnace," the older one said. "Dean!" Sam shot him a look. "Sorry," he mumbled. "I'll get the car keys. Get him outside." While Dean ran to grab the keys, Sam carefully lifted the angel and carried him up the stairs. Within twenty minutes, they were at the hospital, bringing their supernatural friend into the ER.

A male nurse immediately noticed them. "What happened?" he asked calmly. "He's got a high fever. He collapsed at bunk uh, at home," Sam explained. Before the nurse could respond, two more staff members and a doctor arrived with a gurney. Castiel was gently placed on it and wheeled away. The brothers tried to follow but were stopped. "You can't come in. Please wait in the lobby. We'll update you as soon as there's news." With that, the doctor turned and walked away. As always, Dean didn't take orders well and made a move to follow anyway. "Let the doctors do their job. Cas is in good hands," Sam said, grabbing his arm.
