That answer (both are the same article, just published in different places) starts from the assumption that it comes early in the interview.
But our OP said, "I've usually already covered that." So she's apparently getting it later in the process.
But I vote to keep it business.
Maybe now's the time to talk about why you like that job (though in my interviews, I start with that question; but I'm unusual in that, I hear). How does it interact nicely with your preferences, personality, preferences, etc.? So you're revealing something about you -personally- and internally, but it's all related to the job, the mission, the tasks, the company you're interviewing with.
