I think the description of the scheduled pages above and the slate below must mean that we are behind. We’re still on the death of the zombified bartender. The beast must die soon as there’s the rest of the climax to shoot.
I do remember the Winchester scene being as intense to shoot as the scene appears in the movie. It’s a very strange feeling keeping a siege sequence going and maintaining that mood.
As a director you do also feel like you are barricading yourself in the set and not venturing back out into the world. It’s quite the lock in.
