I'm sorry but I don't believe there is reference of Delta in BaS.

Anyway, there are too much difference between B2 and BaS. I just want to believe that there are mainly two universe : Prime Rapture( B1 - BaS + small contents of B2) & Regular Rapture( B1 - B2 without intervention of Elizabeth ).

Actually, I really hate Elizabeth is caused of all Bioshock 1 : Civil War, Protection Bond, and even returning of Jack. It's deus ex machina!!!
