Just before you get to Jayne Wilde, you will move through a grid with a series of cells. You can open these cells to cause a bit of havoc. However, if you stand in an empty cell and project yourself out the door and to the switch outside, you can lock yourself in. Snap back to your body and Vettic will make a comment like 'Well that was clever.' Wait a few seconds and one of the psychos in the cells will run along and pull the lever, freeing you.
