I don't know how the DNA test was negative. We can only guess that Jill is not Katherine's daughter, of course that would be horrible cause Billy and Mac were so in love. They had already gotten married and were on their honeymoon night when Jill bursted in and told them the news, they were both heartbroken. Billy left Genoa City, Mac stayed around for a while and then moved to Louisiana with her dad. I guess that's why Billy became a womanizer, probably scared to fall in love again.
Does anyone else hate watching the scenes with the pshychotic nurse? That's a little off the deep end for me, I fast forward through those scenes.
