When Danny is trapped inside the circle of blood blossoms in Salem, Tucker drags him outside of it. But he's still affected by them, so Sam tells Tucker to eat the blossoms. As Tucker's eating the blossoms, Danny is back to being *inside* the circle.
When the other monks join Danny and surround Vlad, the one who speaks is holding a spear, but in the close-up he is holding a sword like everyone else.
The people of Salem, Mass. never burned anyone at the stake - they hung people instead.
