"Breathe Harry. You know what we need." Sirius instructed softly, giving Harry's hip a gentle pat. Harry nodded, taking a few deep breaths, but still felt restless. After a moment he began moving his hands in small circles, trying to work through the tension building in his chest. Eventually he started moving faster, causing Sirius to chuckle lightly and nudge his shoulder playfully.
"Slow down, love. Don't make yourself sick." Sirius teased, making Harry stop quickly, dropping his hands into his lap. "Sorry, I guess I'm a little tense." He admitted sheepishly, rubbing the back of his neck. "Don't apologize. It's perfectly normal to be anxious. We're going on our first date, after all." Sirius reminded him and Harry couldn't help but beam brightly.
