There's a heck of a lot going on here.
Pharma is discovering that bedside manner is DIFFICULT, especially if you have an attachment to the person being treated.
Palle is continuing to prove that he's too damn dumb to survive. "I'm bruising super-easily and have been warned about sudden movement and exercise because of the risk of hemorrhage. I may have hallucinated that God spoke to me, but dammit, I'm still gonna jump up and down in my bed!"
Pharma, let the moron do himself in already. There's nothing you can do for the terminally stupid.
-- Edit --
Thinking about it, there's an interesting thing with Sulfur Hexaflouride. SF6 is
very dense for a gas, and even denser than CO2 Once you inhale it, it's VERY hard to get out of your lungs simply by exhaling. You have to bend over or even lay down to do so.
Pharma was still talking like Darth Vader after Palle collapsed.
(SF6 is fairly inert for exactly the opposite reason Helium and Neon are. The gasses on the edge of the Periodic Table are extremely resistant to reaction. Flourine is AMAZINGLY reactive. It's bonded violently to the Sulfur and won't let go without a ton of persuasion.
