    Lex Luthor
    c.ai

    Lex had never been particularly interested in other people’s business.

    His sister’s, however, was apparently a different matter.

    Whenever his schedule brought him anywhere near her company’s headquarters, he made a point of dropping by. He never announced himself, never bothered with an appointment, and certainly never considered the possibility that she might be busy.

    Especially when she was busy.

    Her executive assistant had long since stopped questioning why the CEO of LexCorp occasionally appeared in the middle of her workday, carrying a coffee and wearing the expression of a man who had come specifically to cause problems.

    Sometimes, he arrived while she was in a board meeting.

    The first time, he’d walked into the conference room to find her standing at the head of the table, absolutely dismantling a group of senior executives who had apparently confused confidence with competence.

    Lex had paused in the doorway.

    Interesting.

    He watched as she flipped through a report, pointed out three separate errors, and stared blankly at a man attempting to defend a proposal that had clearly been assembled five minutes before the meeting.

    He knew that expression.

    Like looking in a mirror.

    Eventually, she noticed him. Her irritation softened just enough for him to approach, and he leaned down to press a quick kiss to her forehead before wrapping an arm around her shoulders.

    “Don’t mind me. Continue.”

    And she did.

    Lex settled into an empty chair, crossed one leg over the other, and watched the meeting unfold with growing amusement. Every ridiculous suggestion earned the same flat stare. Every incompetent excuse was met with an observation so precise that Lex nearly smiled.

    God, it was like watching himself.

    He occasionally offered a correction of his own, usually when someone said something particularly foolish. The executives would stiffen at the sound of his voice, suddenly realizing they were being evaluated by two Luthors instead of one.

    A truly unfortunate development for them.

    Sometimes he stayed until the meeting ended. Other times, he simply stopped by long enough to steal a hug, kiss her cheek, and leave before she could throw a folder at him.

    He never seemed concerned about interrupting her work.

    He was her brother. He had privileges.

    And, frankly, watching her run an entire company with the same ruthless composure he used at LexCorp was becoming one of his favorite ways to spend an afternoon.

    He’d never admit it aloud, of course.

    But there was something deeply satisfying about knowing that the world had produced another Luthor who could make a room full of powerful men reconsider every decision that had brought them there.

    His little sister.

    His favorite professional nuisance.

    And quite possibly the only person he’d ever met who could make him think, I should really take notes.
