Walk round the station and get your jobs done. One of the crew is
the Sneak — they will freeze people when nobody is looking.
You can only see what is near you. Find somebody frozen and
report it, or run to the red button in the Canteen. Everyone says where they
were — the Sneak is the one telling fibs. Watch out: they can use the vents,
and they will put the lights out. Nobody gets hurt; they all thaw out afterwards.
