The wire is very thin and cuts into your hand as you pull. But eventually it comes away. There's a lot of it, and you coil it up, you'll probably find it useful later on. You scramble through the hole and run. The creature tries to follow you and gets stuck. You're safe... at least until it rips the fence apart. You look at it, wondering what to do. You could wait until it's free to run, or you could use the time to escape.
