Ever since i heard about the small albino drone alien i always imagined it as a tailless version of Gigers Necronomicon creature. Translucent skin, non combatant almost pathetic. I could imagine two or three of them slowly gathering around a freshly laid egg, plucking it and moving it to its designated area. They can also be used to explain the egg in Alien 3. One could have stole away in the landing gear with the queen and, after the queens death and the all clear, would have crept out from the shadows of the landing gear and made its way into the Sulaco's cryo sleep chamber,egg in towe, and placed it near the cryo tubes. Then it could have died somewhere in the ship leaving behing a dead bio mass. Thoughts?
