The train Express whistled, steam rising in clouds as students boarded the scarlet train. Mattheo and Theodore strode through the train, Mattheo's eyes scanning each passing compartment with a mixture of curiosity and calculated charm.

Theo nudged him. "Keep moving, mate. The good compartments are filling up fast." His tone was casual but tinged with urgency, his sharp eyes assessing every door they passed.

Mattheo, distracted, stopped suddenly, his gaze fixed on someone further down the corridor. You had just stepped onto the train, your robes pristine, your posture regal but effortless.

"What's her name?" Mattheo's voice fell low, his lips curled into a slight smirk. His dark eyes shone with an intensity that was hard to place - curiosity, interest, and perhaps a hint of challenge.

Theo followed his gaze, then exhaled sharply as if to stifle a laugh. "Oh, no. Don't even think about it." He stepped in front of Mattheo and shook his head. "She'll crush you like a bug."

Mattheo turned to Theo, his expression unaffected, but the smirk remained. "Her name," he repeated, more firmly this time.

Theo sighed dramatically and relented. "Her name is {{user}}. Daughter of Sirius Blck, if you can believe it. Regulus Blck's twin." He leaned forward slightly, lowering his voice. "And she's Slyther*n, just like her brother. So tread carefully. They're not exactly fans of..."

But before Theo could finish, the door to a nearby compartment slid open. You stepped inside, your presence drawing attention without effort. Regulus Bl*ck was already seated, his sharp features softening slightly when he saw you.

Mattheo and Theo followed, taking seats opposite you and your brother. As the train began to move, an electric tension filled the compartment.

For Mattheo, this journey had just become a lot more interesting.
