Checking the blood
What is the deal with the sniffing of the blood ? It can't be the alien's blood since it's mentioned in the movie that the only thing that can kill the alien is the weapon that Lloyd has. If no one is sure of what I'm talking about it, there are 2 scenes where he sniffs the blood: 1. when they're chasing the stripper up the stairs, there is blood on the stair steps 2. after the explosion in the jail cells when Beck shoots Masterson in the head, there is a trail of blood. Both times Lloyd Gallager kneels down, touches & sniffs the blood & knows the alien will be changing bodies pretty soon. This is after both Gallagher & Beck have shot the alien host so many times that it becomes noticeable. Is it the body's blood becoming contaminated with the alien's or what ?
