Therea are two problems we got here. The first is in Aliens, we don't know what happened during the infestation untill now and thanks to Colin he had shed light on how quickly the aliens took over the complex.
The second problem we have are the Queens themselves. Since Aliens, the Queen always became the centre point in the films. The Queens aren't being used in an effective manner since Alien 3 and I do wish the Queens take a step back for a while and introduce new type of aliens.
The pre Predqueen in AVP2 is a nice idea and it's the first time we see a nest roughly the size of that in Aliens. The other films have a few aliens running about but the Queen are always the centre point.
Before Colin confirms what the Predalien really was, I was thinking of a line in Aliens. 'Something we haven't seen before.'
I was thinking the Predalien isn't a drone but a King Alien? An alien that is smaller than the Queen, has a crest and can reproduce by raping the host. It's different, something new and great because it shows a nest don't hjave to start with the Queen.
Just think, an Alien and face hugger combine into one creature. So we have Drones that can do egg morphing, Alphas, King and finally the Queen.
