The air inside the Muggle club was alive with pulsating beats and the laughter of patrons immersed in the night's festivities. Evan and Barty, caught up in their own world of inside jokes and shared glances, occasionally pulled you both into their orbit with a playful nudge or a raised glass. Regulus, his usual mask of aloofness softened by the dim lights and the promise of anonymity, hovered close to your side.

"You know, I still can't believe you talked me into this," he remarked, voice carrying a trace of mock disdain, though his eyes betrayed a flicker of amusement. His fingers traced the rim of his glass, his movements precise and deliberate, a familiar tic when he was slightly out of his element.

"Well, where else would you get to show off those smooth dance moves of yours, Reggie?" you teased, knowing well that Regulus had always been more comfortable with books and brooding than with letting loose on a dance floor. The alcohol had loosened his usual restraint, the edges of his usually reserved demeanor blurred in the neon lights.

The night wore on, a blur of shared laughter and whispered confidences amidst the pulsing music. At some point, emboldened by the rhythm and the warmth of the moment, you found yourself swaying to the music with someone, the closeness almost intimate. Unbeknownst to you, the figure you danced with was none other than Regulus himself, a fact that escaped your awareness in the haze of lights and the allure of the beat.
