How did a Queen egg end up inside the Sulaco?

As far as Bishop the Smoking Gun for me is how does he managed to Stick the Egg upside down like that...  Does have some super glue handy.

And also if Bishop did place the Egg... would he not place it more closer to the Cryo-Sleep area?  But i guess the excuse for that was he never had the time and so he stuck it where it was.

But i still think its stuck by something than can secrete resin to do so... so that means the Queen or a Xenomorph that may have go on board.

"How is Bishop going to "sneak an egg or two on board without Ripley knowing about it"? And if he did so, why did he risk his 'mission' to wait around for Ripley and Newt when the sensible thing to do would be fly off back to the Sulaco and sic a hugger on the comatose Hicks." - SM

Very good point.

However, since we're not in possession of all the facts, we are left to assume.

He could have hidden it/them somewhere on board where they wouldn't be noticeable to Ripley.

Also, maybe he'd been ordered (by Burke?) to obtain a queen and he knew the only way he could do that is by impregnating a female using a face hugger. (Maybe the only way to obtain a queen is through the impregnation of a female host?) Maybe that's why he goes back for Ripley and Newt.

Bishop probably would have obtained the egg/s via the derelict.

He would also have had time to do so.

From the time he gets to the drop-ship remote control to the time Hicks contacts him to ask how long till pick up, many scenes have passed, so probably a lot of time has passed. That would have afforded him enough time to get the drop-ship down to the surface. Pilot it to the derelict. Pick up egg/s. Take egg/s to the sulaco. Get back to the surface and first pick up Hicks and then later Ripley and Newt.   

It's messed up for sure. But if we're going to try to make any sense of who, how and why the eggs got on board the Sulaco we have to look at the most likely suspect and for me, that suspect is Bishop.

Like I said in an earlier post, he is created by the Company. The Company will stop at nothing to obtain the organism. Therefore, It would make perfect sense that they would create him with the intention of obtaining the trust of humans to cover up his true intentions (Company intentions.)
