Mainly due to Flash Forward.
Like, remember when I was on edge for
three weeks because of the unsettling potential for my beloved Amita over on Numb3rs to die sometime during the Season Five finale?
Yeah, it was sort of like that with Demetri on Flash Forward.
HOWEVER, like Numb3rs it all turned out okay and in THE MOST AWESOME WAY POSSIBLE.

I have some thoughts, and they are spoilery. )
