Lee haunts the caravan
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Lee told Alex the story about somebody called Amy who would haunt the caravan as he made things move around him. He then revealed to Alex that it was him making the thing move as a woman appeared from the toilet with a lot of fog, although Lee claimed he could not see the lady Alex was seeing. He received 4 points.
