What do Wires represent?

Wires are a symbol of threat to Pax. Pax can sense the electricity running through the wires. He also realizes it is the wires that have something to do with the exploding boxes. Pax is able to smell the danger in them just as he was able to smell danger in the fan with the short in its housing. Pax had chewed the wire to the fan because he was trying to protect Peter. He also tries to chew the wires connected to the land mines in hopes of protecting Peter.
