I can finally explain where Crystal went!!! Did anyone notice that in the first few seasons she lived in a smaller house, very similar looking to Roseanne's except it didn't have a porch? Well maybe after Angela was born in season 4 Ed bought themselves a bigger house out of Lanford but not too far, maybe near Chicago. Because if look at her house in season 6 it's much nicer and bigger to look like a house that would be in Lanford. And if you notice after Angela was born that's was she was in less episodes. And I'm sure her and Rosie kept contact through phone it's just she didn't come around a lot since it was far away. I just thought I'd explain it a little more instead of just saying it was because she had more kids.

I WOULD HAVE NEVER THOUGHT OF THAT! I'M NEW HERE AND I ALSO JUST WANT TO SAY HELLO.
