I had absolutely no idea! This show is brilliant, and it would never have occurred to me that Haley was so ill. I wonder why it took so long for her to be transplanted? What do you think the doctors were waiting for? It just seems like she's been suffering needlessly for so long. Typical....they tell you only bits of the story.
Anyway, I'll be eager for next season of Modern Family! I guess CKD and dialysis doesn't really fit into a comedy.
