In S1E12 of Fringe, "The No-Brainer", a jobless computer programmer creates a computer virus that kills people by liquifying their brains. It looks as if a hand protrudes from the screen, grabbing the head of the victim.
All events we've seen until this episode are connected to the pattern. This seems to be a standalone case.
I haven't watched very far past this episode, although I'm in the process of watching the entire series (so I don't want to be spoiled too much). Is this case indeed unconnected to the pattern?
