Holy shit, the queen? David is actually talking about a queen? Huh...
Crap.
Speculating here, perhaps, just perhaps, this 'queen' could be the one who births those eggs in the juggernaut found in LV-426, instead of the egg morphing theory that's been thrown about recently. Though, now knowing that Fox is reassessing on what to do with the prequel trilogy, we might be left with only speculating and theorizing.
