boyfriend  has been shot, John knocks over the refrigerator and they hide  behind it. The next scene shows the shooter looking through the  sights on the EM gun, which clearly shows the grid on the back of  the refrigerator, placing it on its side. When the projectile  grenade goes off, John is shown lifting the door of the refrigerator  up by the handle to shield them from the projectiles. If the  refrigerator was laying on its side, he would actually be opening  the other side, not the door, which would be facing them.
