Marlena and Missed Opportunities

After Marlena was left alone in the secret room the first time, why didn't she break one of the plastic coat hangers and use it as a stabbing weapon?  Or use one of the dresses to unscrew the light bulb from the socket, break it and use it as a weapon.

When Stefan came back and she was holding the book to her chest while talking to him, why didn't she thrust it upward and break his nose?  LOL, she needs to come train where I do.
