The elevator lurched upwards, then suddenly went into freefall for a
half-minute before stopping dead. Keats, Amber and McJohn were thrown
about violently.
"What the smeg --" shouted Keats.
"Someone's messing with the master lift control!" Amber shrieked in
reply as the elevator jumped up ten floors in two seconds, then
dropped into freefall again.
"Don't worry Jean, I'll get you outta this!" McJohn yelled as the
elevator came to a dead stop once again.
"I'M NOT SMEGGING JEAN HARLOWWWW --" Amber screamed as the elevator
began streaking upwards once more.
Finally it ground to a stop and the doors opened. The three occupants
found themselves face to face with figures who looked like Jack and
Jay. McJohn screamed and brought his blaster up to fire.
