We've heard everyone's perspective.
And I've discussed each one before in earnest with consideration, but "it's a dream opening"
is the only one that doesn't require a fifteen minute exploration.
Spoiler
Although the "ooze" theory's got a certain appeal for the fan in me,
as one ooze deposit means one Egg, means one Facehugger,
which means the 2010 Special Edition's definitely canon.
But it's a retcon from a coffee table book, (no offense, I love the book myself)
and the dream theory means you get to choose between all three versions as it remains ambiguous.
My vote? Lock the thread.
