In the episode, Dr. Izzie tells the interns to diagnose Patient X, whose real identity she doesn't disclose. What they discover is that the patient has metastatic melanoma, which is a skin cancer, and has spread to her brain.
One of the interns even says, “This girl’s pretty much toast. Survival rate is five percent.”
So does this mean Katherine’s really leaving the show? It’s going to be hard to stick around with a five percent survival rate!
According to Us Weekly, a set source says, “Shonda and the writers are pissed at her. It's their way of screwing with her. She won't know whether she's going to live or die."
We don’t have a real confirmation from Heigl yet, but all signs point to yes. Why would other cast members like James Pickens chime in and say she’s leaving just to stir up drama?
It sounds like Katherine Heigl has pissed on one too many people on that set, and she’s getting what’s coming to her. Guess a brain tumor is Grey’s version of falling down a mysterious elevator shaft…
