In the third dream scene (the reverend's dream), everyone has been made to look older, except Rolly who has a bionic hair transplant. We learn that Thelma and Reuben have had ten children and there's another one on the way. Since Thelma is about 35 when she marries Reuben, that means she would be close to 70 when she's pregnant with their last kid! The Gregory offspring are all boys, and their names are Reuben Jr., Peter, Paul, Joshua, Mark, Luke, John, Abraham, Isaiah, and Matthew. On the very last episode, Thelma gives birth to the first child, and it is indeed a boy. Its name is not given, but perhaps we can assume it is Reuben Jr., like this scene indicates.
