Overview:Things have gone missing and Gordon has closed the centre for the day. He explains that there could be a thief about and sets a trap to catch the thief. The plan is to hide in a locker and sees who takes the bait (his wallet). Meanwhile Helen is suffering more stress then ever and takes Gordon to see the doctor leaving Colin to hide in the locker. That afternoon it turns out there isn't a thief but Colin is left hanging on the rail still in the locker.
