Advantage
The boys started to talk about which of them should cut off the leg, but none of them wanted to do it. Vorden knew first hand what the pain was like, and argued that he had already done his part, while Quinn was the one who cut off Vorden's leg. In the end, it was a unanimous decision that Peter should be the one to do it.
He had similar strength as Quinn so he should be able to cut it off clean. Peter grabbed the meat cleaver from the kitchen counter and walked over to the female all the while Vorden and Quinn held her down on the floor.
This time, they had also put several towels where the cut was supposed to be made, in order to not make a big of a mess like the last time.
The two had to hold her down even though her mouth was already gagged. Furthermore, she was blindfolded, but she had heard the whole conversation going on between all of the people in the room. At first, she thought it was a twisted sick joke being played by her friends.
