In Super 8, the monster took a number of humans prisoner. Why? Why take them back to its lair and store them, unconscious?
It is seen taking one human prisoner down, and doing something with them, and it was in the process of taking Alice down as well before it was interrupted. What was it doing with them?
It seemed that it most likely killed some of the prisoners, in particular the sheriff and the other woman who tried to escape, but why keep them alive until then (especially since the sheriff was likely the very first human captured)?
