So Gates...you want Aliens simple? the idea doesn't break canon because nothing said they can't do it and we've never seen a sitation that'd they need to or have enough time...
A1: for one the ship is to small for a Queen...that fact aside, i doubt the molting is a split second thing (which if it was would make me angry) time, less than twenty four ours being alive, not enough hosts to do anything.
A3: Queen on the way don't need to molt.
And i'm surprised that Alien fans of all people would say "Because we haven't seen it...it can't happen." that isn't a good way to think about anything
and for extra measure.... Y didn't they see it in AR?
i thoguht a couple reason...The Queen saw no need to use it so used the egg sac, AR docs weren't smart enough or didn't know what to look for. and third reason maybe it only works for Aliens molting into Queens...
ok i'll pause and wait for you to skim over this and just call me stupid...
