No less quick on your feet, you opt to snag the piece of blue fabric you dropped. In white print, there is indeed something written on it.
You don't recognize the number, and honestly you can't be sure if you should or shouldn't at this stage.

Then again, there's all kinds of crazy gibberish with those four strings, and you would assume that you'd need some unattainable knowledge in order to figure it out.
