When Strand and Samuels, the female ranger, return to the site of the convoy, she is holding her rifle. When the first dead ranger gets up, however, she pulls it from its sheath.
The dead have surrounded the lodge and manage to break down the left door (of the double doors) taking it off of its hinges. The camera shifts to the wounded Ed pleading with Alicia not to betray Dakota (and other scenes). The camera continues to show the left door off its hinges, then to Alicia and Ed, and Dakota. But then the camera shifts back to the double doors, and the left door is back on its hinges. This time the dead break down both doors, popping both off of their hinges.
When Ed summons the dead to surrounded the lodge, they break down the left door (of the double doors), popping it off of its hinges. The dead stick their hands around both sides of the door, as well as over the dislodged door. After a few scene changes, the door is back on its hinges, and the dead to break down both doors (popping both off of their hinges, and therefore popping the left door off of its hinges a second time).
