If you asked William what he was thinking when he restarted the long dormant supercomputer, he wouldn't know what to tell you. Maybe he wasn't thinking at the time, or maybe he was too absorbed in his own nightmares.

I decided to rewrite Season 2, focusing only on the main plot line! There were some things I didn't particularly enjoy and thought they could be improved, so that's what I did. I wanted to improve the involvement of the group in the Hopper investigation. In my opinion, only Jeremy focused on it and the others didn't seem to be interested. Enjoy!
