I've heard the suggestion that the finale should be about the team having to diagnose how House died, or something like that.
Yeah, Snaploud came up with the idea
and you added the best part... The episode ends with House saying "Morons!"
When I was trying to remember that discussion here
, I had the episode ending in a misdiagnosis and House saying something to the effect of... "It was lupus. Idiots!" Thanks to Allyn Gibson
for putting the lupus bit in my head.
