Potential spoilers about Heroes, circa Six Months Ago

I just finished watching Six Months Ago, and was promised by the Announcer Dude that something shocking would happen in the next episode. I’ve always thought I was rather good at deductive reasoning (as regards fiction, anyhow), so I thought I’d take a stab and see if I can guess the shocker. I’m probably not as good as I think I am, but if you’d like to read it, you can.*

*I should note that if you’re current as of Six Months Ago and you want to be surprised, my speculation might ruin things for you.
