So that fans of the series would not be left completely in the dark after the second season, Heaton also gives some hints as to what the possible third season might look like. “PS – Jack totally wanted to raise Alyssa from the dead, but she’s going to come back wrong. Like, Pet Sematary wrong. It was probably owned by Zecchia. And a whole bunch of other corpses were coming back with her.” Heaton in another tweet.
