She can, but Lazzar can't. But, I suppose multiple skill challenges offered advantage. If there's any non sneaky ones that the ninja girl can help with before sneaking she could offer to help roll for Lazzar.<br/><br/>Lazzar herself would probably want to try disguising as staff. She has quite good odds at making it too, at least making most of the rolls. I suppose between the two of them there's not enough computer skills to hack the vehicle though ;D
