Niska thinks that this man could be extremely helpful or extremely dangerous and she's not sure which side she's landing on yet. Anyone who knows this much code could be useful, like Mattie, but if he found out her secret, then she would be at risk and after so long passing as human, it's not something she wants to test out.

Instead, she'd much rather pick at his comments, diving in to try and understand it better. "Avoiding the lists?" she asks, narrowing her eyes at him as she leans casually with one elbow against the console, a perfect mimic of a human being. "Can you really look for coding signatures and ignore a main piece of information right in front of you?" she challenges.
