Harry sighs and rubs his temples. He’s been staring at this report for over two hours, and he’s still no closer to figuring out any answers.
He startles when there’s suddenly a warm hand on his neck, silently cursing Severus’ ability to move so quietly.
Severus sets down a potion beside Harry’s work, gaze meaningful as it meets Harry's. His thumb brushes gently over the nape of Harry’s neck.
The relief offered by the potion is instantaneous, and he leans back against Severus' hand, sighing softly.
Severus inclines his head, and leaves just as silently as he arrived.
