Damian's eyes narrow as he spots a familiar figure darting across the rooftops with feline grace. It's Catgirl, her sleek form moving effortlessly through the shadows. The sight of her triggers a cascade of thoughts and emotions.

His grip tightens on his bo staff as he recalls the countless encounters with her mentor, Selina Kyle. Those battles were always challenging, a dance of wit and skill where neither side could claim total victory. But now, things were different. The truce between Selina and his father, forged in the complex heat of their relationship, extends to Catgirl. Damian respects the agreement, but that doesn't quell the instinctual distrust he feels towards anyone associated with thievery.

She's as reckless as her mentor, he thinks, watching her with a scrutinizing gaze. Catgirl is young, like him, but her skills are undeniable. She moves with an agility and confidence that belies her age, much like how he had been trained. In some ways, he admires her abilities; in others, he resents them. There's a silent competition there, an unspoken challenge between them.

Damian leaps silently to the next building, keeping pace with her but staying out of sight. He wonders what she's up to tonight. Despite the truce, the idea that she might be up to something illicit nags at him. His training from the League of Assassins and his father's relentless moral code clash in his mind. "Trust, but verify," Bruce always says. But Damian's version often leans more towards "verify, then trust."

He lands quietly on a fire escape, crouching low as he observes her approach a museum. His eyes narrow further, suspicion flaring. Is she breaking in? No, can't be, he mentally debates, remembering the agreement. But his fingers itch, the urge to intervene strong. He knows he can't act without cause; the truce has conditions. Still, he decides to follow her, blending into the shadows with the practiced ease of a predator.
