The title says it all. And this is spurred by a comment posted to this post on the “Movies & TV” site here.
Does the queen get to choose when the eggs open? That's not how it works with any egg laying creature I've heard of. But if Ripley attributes the egg opening to the queen's intent that might explain her behaviour. (Although the queen coulda waited another few seconds 'til Ripley wasn't looking!) – Grimm The Opiner
The general gist is whether there is any in-universe citation that explains how much control the Alien Queen has over the eggs and other aliens around her?
Specifically, there is this scene in Aliens (1986) (around 2:38 in) where Ripley confronts the Alien Queen and an egg opens up—seemingly on command of the Queen—right in front of her.
My interpretation of that scene—as a casual viewer—has always been that the Queen is in control and somehow able to make her eggs open at will like that. And yes, earlier in that clip the Alien Queen seems to order other, full-grown aliens by glancing at them, but that doesn’t really explain the egg near Ripley opening up like that.
Am I wrong in this assumption and the egg simply opened because a human was detected near it… And if that is the case, why only one egg and not all of them? Or at least a few more given the density of eggs in the reactor at the time.
Looking for an in-universe, canonical explanation. If one does not exist, something that can get as close to in-universe and canonical is acceptable.
