First off, tell the Doc about her. Second, does she think SHE is not going to die. HELLO, we all will die someday, she doesn't have some exemption. If she tells you that again, say "So are you"...
You know what's funny? That nurse that you all think is evil probably cares more about kickstart than anyone thinks. She just has no sense of tact whatsoever and has no idea how to express herself right. Of course she is wrong to accuse a patient of not taking their meds when the patient swears repeatedly that she takes them. It's also obvious she shouldn't be telling any of the patients they are going to die. But if she didn't care would she even bother? She would just ignore KS and her problems. Maybe she cares too much, and doesn't know how to express it appropriately. Seems like KS is going through a lot and it's an emotionally charged issue for everyone involved. Strong emotions often cause people to say things they later regret.
