Chloe - this has been really bugging me - question..

I admit, I don't watch regular anymore. I check You Tube once in a while but I do read the mags and online and such, but I'm lost.

Correct me if I'm wrong - these are the facts.

1. Chloe has survived leukemia
2. Chloe has two parents - one a well known doctor - who dropped their lives to save the life of their new daughter
3. Brady, the "love" of Chloe's life (and here I thought it was Philip, but now it's Dan?) was with her throughout her entire leukemia ordeal and it proved to Chloe the depth of their love (yea, I know, subjective, but it's a fact)
4. Philip, the "first love" of Chloe's life was there when the leukemia was found in high school. He was there through her treatment.
5. Both Brady AND Philip are in Salem currently.
6. Chloe is now married to Lucas.
7. Chloe is having an affair with Dr. Dan
8. Kate knows Chloe is having an affair with Dr. Dan and trying to make them pay.

Kate is POISONING Chloe right? Kate KNOWS Chloe is a leukemia survivor. Chloe hasn't been feeling good. Everyone knows her history, but no one knows about the poisoning and NO ONE is calling Craig and Nancy? NO ONE is questioning the return of her leukemia? The FIRST thing they find is poisoning? HOW come no one bothers to check a blood count to see if the white cells are bad? WHY is there no mention of calling her parents - who would fly across the world for her? No calls to Mimi, Belle, Shawn - hell they don't NEED to be on the other end - how many times has Eric or Carrie been called with no one on the other end?

THAT is driving me nuts.
