Remember, according to Dr. Marston, she is only bound until she wants to break free.
This knot sucks. I haven't figured out anything to do with it. I must have to work on my detective skills soon. I hear that the figure eight is the basis of many other knots but I don't really see any use for it by itself. I guess it could stop a rope from going through a hole or something.
In an case, this is how you tie a figure eight
1) Make a loop.
2) Bring the working end around the standing end.
3) Feed the working end through the loop.
4) Pull to tighten.
