Marinette can't help but to blink, tilting her head at the small creatures. "Yes? Am I not supposed to....?"

Because they were right there. She's not sure if others usually can't see them? But even Chloe had seen Tikki before, and assumed her to be some sort of toy at the time, given Tikki playing as one. So she's probably safe in admitting that much, right? Though if they also sense something the same way Tikki did, they probably suspect her already as another with a kwami of her own.
