Gwen is not exposed until the last few minutes of the show.
Ethan and Theresa get married during the last few seconds of the show, and die together in each other's arms.
note, there have been many sources saying that everyone does not die in the very end. according to the last part of super spoiler, they included a pic showing the church being flooded with lava and ethan and theresa holding hands. they also showed a picture of the entire cast saying good bye. they confirmed everyone dies at the end, and the ending is very open ended (meaning that it looks as though it can be continued)
Mount Harmony erupts and everyone hides in the church.
A heavenly source tells Kay and Endora that Tabitha needs to be baptized to stop the volcano.
Father Lonigan refuses to bapize Tabitha.
The article also says the ending is very rushed. In the last 15 minutes of the show, Gwen is revealed, the volcano erupts, and Ethan and Theresa quickly get married in the last 30 seconds of the show so they die as a couple. At the end everyone dies with the ppl they love (shuis) >(
