What are the plot holes in the Alien & Predator movies?

No one is perfect and I am sure there must be a few. So...What are the plot holes in the Alien & Predator movies?

Probably not a plot hole, but I always thought that the dragon should take Ripley in order to the hive to protect the Queen.

There's three of them on the inner edge of the derelict. Dallas & Co. enter through one.

Didn't Kane go down one too?

They couldn't keep him out of it.

Oh my goodness, it's Riddled with them!

I see what you did there.

On a serious note, I honestly can't think of any actual plotholes in the first 3 films.

There's the egg on the Sulaco, but that has its own thread.

Drake was full of holes after the acid bath.

Yep. Seriously, there have been some fiery discussions of the definition of "plot hole"., and the lack thereof.

People often mistakenly call a continuity error a plot hole.

Let's split the difference and call it a continuity hole.

[SiL]

A plot hole is a hole in the established logic of a film. It's not a continuity problem, an inaccuracy, or something someone finds weird.

Fifield getting lost, for example, is a plot hole: he's established as the guy with the mapping software leading everyone through the structure. Then he's lost with no explanation. This is a hole in the established logic of the film.

The egg being upside down on a random piece of ceiling on the Sulaco is a plot hole, but an egg being on the ship isn't (there was, after all, an egg laying monster on the ship at some point).

^ All that.

So when did the queen glue the egg to the ceiling?
