Trying to keep her cool in spite of her desperate situation, Natacia goes about in figuring a way out of her predicament.  She started by searching for anything in the cell that might be used as an impromptu weapon, unfortunately she had no luck there after going through every inch of the room.  The manacles could be a possibility but after testing them they seem to be firmly secured and well maintained, no doubt meant to hold very troublesome prisoners.  It is the same thing with the door, the only the way possibly breaking it open is if she were an ogre or something with similar or greater strength.  It looks the bowl of gruel is her last resort, if at all it would be useful.
