The only contradiction with the whole Suchong thing and the Delta/Eleanor thing isn't that big. The protection bond still couldn't have been perfect, like Gil said, which is why he was brought on to the project. Even then, Suchong said in an Audio Diary early in the Civil War that he will use the recycling of corpse ADAM blood and the Big Daddies to protect the Little Sisters because of all the bodies from the war containing ADAM.

If anything, BioShock 2 retcons BioShock 1. I loved BioShock 2, but I really don't consider its relationship with BioShock 1 since Ken Levine didn't write it. I know that Ken Levine isn't the only person who has worked on BioShock, but really, Ken is the father of the BioShock series and Jordan Thomas is the step-mother of BioShock 2.
