A woman named Brenda wore a red cloak and a pig mask, chained to a device with numerous gears and a dial, trapped in a room in Rigg's home. A tape recorder was duct-taped to the palm of her left hand, and her long hair was twisted though a metal ring and wound up along an axle connected to the gears. She was stuck in a room with numerous pictures of herself posted and hung up around the room, with the words, "SEE WHAT I SEE" scribbled above a bookcase beside her. Rigg entered the room, setting off the timer which began counting down from 90:00, and found Brenda panicking, trying to escape her chains. A TV in front of her turned on, and Rigg was told that she was a criminal. Jigsaw advised him to just walk away from the situation and let Brenda die instead of giving into his obsession of saving everybody. Rigg pulled the pig mask and cloak off of the woman, pulling a trigger-pin that was attached by a cord to the mask,[10] activating the machine. A one-minute timer began counting down as the gears on the device began turning, arching Brenda's head back as her hair was yanked and wound along an axle. After having her gag removed, Brenda screamed for help, telling Rigg to hurry, and that the combination for the dial was on the cogs. She continued to scream for help while Rigg scrambled around looking for something to stop the device. Upon opening a drawer looking for a knife, he found a card that said "Time is wasting." Brenda's hairline ripped and began to spurt blood. Rigg tried shooting the machine with his handgun, merely slowing the machine down for a few seconds before it continued to tear Brenda's scalp from her head. Rigg began reading numbers on the cogs twisting her hair and programmed the code, 6-4-7, into the dial on the machine, releasing Brenda.
When he turned his back, though, she grabbed a knife from underneath the TV set and attacked him. Throwing her into a mirror, he took the knife, noticing a "G" written on it, and ripped the tape recorder from Brenda's hand. The tape revealed that Jigsaw told her that Rigg was a cop who would arrest her if he saved her life; the only way to prevent this from happening would be to kill him. While leaving his apartment, Rigg found a card, next to two keys, that read, "One saves a life... one takes it away." The first key was for a room in Rigg's second test, while the second key was for Rigg's third test. When the police and FBI arrived at Rigg's apartment, they found Brenda dead from her injuries. They also found the words "FOUR WALLS BUILD A HOME" written in illuminated paint.
The point of this test was to see Brenda as a criminal as Jigsaw would have, not as a victim as Rigg believed.
