No not screwing with canon, screwing with hu-mans. We'll learn that the second Bishop(A3) was already on board the Sulaco and we'll watch him glue the egg upside down. Half Bishop will then ask Bishop2 why the hell did he do that. Bishop2 will say he hates insurance adjusters and will take joy in knowing once he turns the security system back on the industry will collapse while they try and make sense of the asinine footage.
To explain why it took company so long to get to Fury... nah not too long. They wanted to arrive just at the right moment and secure the cargo while it still was in it's chest buster stage. Essentially Bishop was going to grab the alien as it erupted from Ripley's chest. A nice and simple in and out but that one Asian guy was a little too gun happy and blew the entire set up.
