Kalinda had already pulled her hood up, causing her suit to activate, and come invisible. She shifted, watching the others head in, before going in herself, beginning to search, she was ready at any moment to throw a knife or dagger, or any of her other weapons. 

She did so at some of those that would come too close to the others, but when she was out of sight, she just kept herself ready, moving as quite as possible. She stayed to the shadows, even though she was invisible. 

She had learned to sneak from a young age, to sneak passed her mothers bed room without waking her. She had learned how to not leave a trace, and she used those skills here.
