Other mistake: At the end, when a policeman pulls an arrow out of Franklin's shoulder, there's no sign of pain or blood, on the arrow or on Franklin's clothes.
Other mistake: When Malcolm is found dead with an arrow in his chest, the arrow is pointing down at an angle, which means it came from someone high up, but, later, we find out it came from someone of around the same height and standing on the ground, not high up on a ladder, or on a rooftop, which it should be, to get that angle.
Chosen answer: As far as hanging new wallpaper, there is no need to brush on any additional product once it has been pasted to the wall. It appears Helena may be doing an extra decorative step by applying a liquid glaze over the wallpaper to give it a more distinctive look, perhaps creating a sheen effect on the surface. Glaze can also be tinted to give a muted colored tone. It could also be a protective sealant. However, to remove old wallpaper, a product is brushed on that dissolves the old paste so the paper can be easily scraped off.
