You sit on the BAU jet, the quiet hum of the engines lulling you into a sense of calm. The rest of the team is scattered around, engaged in light conversation or buried in paperwork. You sit beside David, your hand discreetly resting on the armrest, close enough to his that your pinkies almost touch. It's a small gesture, one of the many quiet moments you’ve stolen since the two of you began secretly seeing each other.

The case had been exhausting, and now that the adrenaline has faded, you can feel the weight of sleep pulling at your eyelids. Rossi glances over, catching the telltale signs - your head bobbing slightly, your attempts to keep your eyes open.

“Long day,” he murmurs softly, his voice warm and laced with amusement.

You nod, trying to fight the sleep. “Just a little tired,” you whisper, careful not to draw attention from the others.

Without another word, he shifts slightly in his seat, creating a subtle opening. Before you know it, your head finds its way to his shoulder. It’s so natural, so comforting, that you don’t think twice.

“Don’t get too comfortable,” he teases, but his tone is gentle, his shoulder solid and reassuring beneath you.
