By accepting that Bishop is the reason, youre accepting that:
1) Bishop got hold of an egg somehow. He couldnt get it in the lab because the lab only had facehuggers, not eggs. He also couldnt go into the hive - we see remotely piloting the dropship and he doesnt go anywhere else. Then Ripley goes into the hive, theres no Bishop there. He didnt follow her and even of he did somehow, Ripley blasted all the eggs anyway. And he couldnt land anywhere there anyway
2) He hid it on the dropship and went to pick up Ripley
3) They return to the Sulaco, land, then Bishop gets ripped in half by the queen
4) After the survivors (including Bishop) are in stasis, he somehow wakes up (despite the fact that Ripley programmed the tubes), drags himself out of the stasis chamber and drags himself to the dropship.
5) He then hauls himself aboard the dropship, finds his hiding spot for the egg, hauls it out of the dropship and into the armory on the Sulaco (an impressive feat with no legs and just 2 arms to move himself and the egg!)
6) He then somehow sticks it upside down under the table or something, whilst still basically just being an upper torso.
7) He then drags himself back to the stasis pods and climbs back in.
Its much easier to accept that the queen simply laid an egg while on Sulaco to ensure the survival of the species and the egg got sucked in in that position because of the air coming out through the airlock. This theory is also filled with holes but its still more logical and plausible
And I agree, Bishop was a good guy, let him rest in peace!
