Spider's Corner

Tim was turned by the operator when he was a kid, and he learns to live with it. Later in life he hangs out with the gang, and the Operator gets its fangs into Alex, who can't handle the sickness. (The Operator constantly stalks its victims)

Alex attacks Seth and kills him because he had no control over himself. He discoveres that it keeps the operator at bay for a while. Alex then decides to try and appease the Operator by offering him the victims. He incapacitates and offers Brian, so he assumed he was killed (really just transformed, but nobody knows). This is when everything/everyone disbands. When Jay gets the tapes from Alex, Alex attacks and infects him. It's latent and doesn't kick in until Jay sees the Operator in tape years later.

(The Operator is a trigger for the others to transform because he is an ancient werewolf. The sight, smell, or sound of the Operator alone is enough to trigger a transformation.)

Later on, during the 7 month timeskip, Jessica gets infected by Jay accidentally. Jay was still unaware of his state at that point.

Tim feels guilty and responsible for all of this, wants to hunt down, and stop Alex from harming more people.
