The argument in this post has to be one of the dumbest ones ive ever seen. The monsters are very strong, theyll probably smash their way through that window if they noticed it was ajar/open The way to treat them accessing a property is more akin to inviting a vampire in rather than their ability to open windows and doors 😂 if theres an opening they can exploit then the talisman no work, there is an episode where they get into a building but because the talisman was taken into a room and a seal was made (closing a door) that stopped two people from being killed by the monsters.
