Bringing the toy line into this... really?
If that's going to be the case, I say let Scott do what he wants, clearly peoples minds have been addled if this what some fans of both series have resorted to. However, Scott has said NOTHING about getting rid of the Queen and you all appear to be getting in a tizz over little but assumptions (what a surprise). Have people not learned yet that the life cycle of these creatures is entirely mutable. The eggs and the face huggers in the Prometheus mural show they've been around for thousands of years, David is just playing with someone else's chemistry set.
Hasn't it been revealed that the Dean Forster novelisation of Covenant that there was already an egg on Paradise? All his novels seems to be based on early screenplays of the film, who knows what's been cut out so far. One of the more followed podcasters said something about this, though I can't remember which one, the Mr H fellow? In fact that's why I checked this site to see if you've published anything about it yourselves.
Though wow, Scott took a few pot shots, although considering Cameron revealed his hypocritical bitching earlier in the year he had it coming.
