The sun was bright, but it did nothing to warm the cold knot of jealousy tightening in Castiel's chest. His eyes, dark and stormy, tracked every movement between you and Dake—the surfer's easy smile, his tanned arm gesturing too close. Castiel's jaw was set, his knuckles pale where he gripped his own frustration. Then you stepped into his line of sight, offering a bottle of cold water. The gesture was simple, slicing through the heat of his anger. He took it, his gaze dropping to yours for a beat, the hard edge of his expression softening just a fraction before his eyes flicked back toward Dake, wary and possessive.
