Connie was very twisted by GFIII. GFI she was the spoiled, starry-eyed brat daughter who couldn't see how she was totally played by this man she married; GFII she became hardened and became some trashy, rich woman with nothing else to do in life but drink, party, speand her family's money and berate her family at every turn. GFIII, she was the family female presence who embraced all of her family's criminal pursuits and came across as some sexless old maid that lived with her shady brother and got her rocks off by helping them plan murders. Far different cry from I Connie that looked down on her family's dealings and was more of a joke than anything else. In her heart, she knew Michael did something to Fredo but she couldn't admit to herself that her family had become that twisted. So she pretended it was all an accident, to herself and Michael.
