As they settled back onto the couch, the movie's chilling soundtrack adding to the tension in the room, Y/N couldn't shake the feeling of unease that lingered in the air. Castiel's presence offered some comfort, but the fear of the unknown still gnawed at them.

Y/N's voice was barely above a whisper as they spoke, the words filled with a nervous tremor. "Do you think we're safe here, Castiel? What if there's something... supernatural in the house?"

Castiel's gaze shifted from the TV screen to Y/N, his expression unreadable. "I will protect you, Y/N. There is nothing in this realm that can harm you while I am by your side," he said with unwavering certainty, his angelic presence a reassuring anchor in the darkness.

But as the movie's tension reached a peak, a sudden crash echoed from the hallway, causing Y/N to jump in fear. Castiel's eyes narrowed slightly, his instincts on high alert as he rose from the couch, ready to investigate.

Y/N's heart raced as they called out to him, the fear gripping them tight. "Be careful, Castiel. Please, come back to me," they pleaded, the vulnerability in their voice a stark contrast to the strength they usually projected.

Moments later, Castiel returned, his expression calm but grave. "There is no immediate danger, Y/N. But we must remain vigilant," he said, his voice steady and soothing, a reassuring presence in the midst of uncertainty.

As they settled back onto the couch, the movie's suspenseful climax sending chills down their spines, Castiel's hand found Y/N's, a silent gesture of comfort and protection that spoke volumes. In that moment of shared fear and anticipation, they found solace in each other's presence, weathering the horrors of the movie scenario together, their bond growing stronger with every heartbeat.
