I know there are "deleted scenes" where Dallas and Brett are shown cocooned, but how could that happen? Well, I guess one Alien creature could do that part, but what's the point if there are no eggs/face-huggers to use on them? From what we're told in the Alien Cinematic Universe - ACU - a "queen" has to produce the eggs, but that can't happen because there's just the one Alien that's running around and can't become the "queen." And nobody else can be turned into an Alien without an egg/face-hugger.

What do others think was supposed to happen?
