Twilight shocker to me at least

I was looking at my new book and I saw something that surprised me. The part when Edward saved Bella from getting hit with the I saw how Edward did it. It says exactly in the book."We formed the aluminum over the real door to get the shape to match perfectly. Then we flamed a hole out of the middle where we wanted the dent to be,and put these sheets on top of that so he could bend and push that section back".
