Was number 5 the one he injects in the eye? I'll have to go back and re listen. Number 5 was the one that had its arm broken off at the elbow in the truck when Lizzy first sees one on the was to the arena with Tardust and Bricks. So if it was then #5 regrew an arm or he bled out or ink killed him and tattooed a new #5 or something.
