In season 1, episode 9 (Home), there is a scene where a spirit opens a fridge for a toddler. The child crawls into the fridge to get a sippy cup of juice, and once he's all the way in the door slams shut and the child safety latch locks. However, a few minutes later, when the mother finally checks the fridge while frantically searching for the boy, the safety latch is undone. She grabs the dangling end and pretends to undo it as though it had been latched.
