This was in this week's TV Guide for a Sweeps Preview:
Halloween Party: Lee and his partner (I can't remember is name) are going to throw a Halloween party. Andrew will be dressed as Cher, Bree as Little Bo Peep and Danielle will come dressed as Bree. How clever.
Adam (Katherine's husband) will be Frankenstein. Somehow he will find out about Danielle being the "real" pregnant person. I assume she will go into labor, and he will be there to deliver. I also assume he will be keeping the secret - for now.
Adam and Katherine had to leave Chicago because of something involving Adam. Lee knows about this. So for now he will share. There may have been something mentioned about Lee having a secret as well, I can't remember.
Also, the CPA appears to have made Carlos' money disappear, so Edie cannot hold that over his head. But Gabby finds out about the money. And Edie hires a PR to tail Carlos, so she finds out about him and Gabby.
It is revealed that Mike's dad is in prison for murder.
Woo Hoo! I love me some Arkie!
