The last episode of "Under the Dome" showed the dome falling and the five survivors being placed in a military base. They were forced to sign a statement blaming Aktaion Energy for all the chaos that ensued while the dome was in place. They were also given new identities and they promised that they would never contact anyone from Chester Mills or speak a word of the things they saw.
However, the final episode titled "The Enemy Within" didn't end there as it went into a one-year time jump wherein Jim was elected to congress. Dawn was shown alive after surviving her fall and going on the hunt to look for more black eggs that produce domes.
Although the finale ended on a cliffhanger, executive producer Neal Baer said that the show won't be returning for another season. The series was cancelled by CBS earlier this year, and Baer also said that he wasn't planning to have the show picked up elsewhere.
"I'm very happy with this ending," Baer told TVLine. "I feel very satisfied. We made it so there could be another [season]…but it wasn't necessary."
The executive producer said that although he's satisfied with the ending, there is one more storyline that he wished he was able to explore.
"The only thing I wish we could have done is bring back everybody in avatar form — Angie, Linda, Dodee, Reverend Coggins," he said, adding that he would have loved an avatar scene wherein the four are haunting Jim.
Baer also talked about author Stephen King's involvement in the show, as the series was adapted from his novel of the same title. The producer said that the novelist has been a "wonderful voice of reflection" and was very supportive all throughout.
On what a possible fourth season would have looked like, Baer said that the remaining characters would have gone to a different place, and the dome would come down again on that place.
"But then it would be like, 'Then what?' Would we do the same thing again?" Baer said.
CBS announced that it was cancelling the series last month, and it appears that the cancellation was due to the show's steady dip in ratings. According to the numbers gathered by TV-aholic, "Under the Dome" premiered in June 2013 with an average of 13.5 million viewers, but its second season failed to do as well as it only averaged 7.2 million viewers. During its third season, the show reportedly hit 4.6 million viewers at its last tally.
