The episode "The Tear Collector" ends with Prudence happily walking off with the cab driver she met after running out of Ambrose's house with her tear bottle, which she dropped and smashed due to the cab.
Ambrose: Prudence! There's too much sadness in the world already! Please let go!
The ending of "Word Processor of the Gods". Richard finally got the life he wanted.
The ending to "The Spirit Photographer" in a... weird sense... Algernon Colesbury is 100% okay with the fact that he died, and moves on with a smile on his face.
"Ring Around The Redhead". Billy is about to be executed for a murder he didn't do. Before the execution, he is interviewed by a journalist named Adele. He tells a strange tale about finding an inter-dimensional portal and then caring for a beautiful woman named Keena who falls through it. Eventually, her people took her and the portal back by force and killed Billy's friend for trying to exploit the portal for profit and killing someone with it. Adele dismisses this as nonsense. Billy is strapped to the electric chair and the switch is flipped, but Keena appears and freezes time. She explains that she told her people that she loved him and convinced them to let her save him. They teleport back to her home world. As time unfreezes, everyone is baffled that Billy vanished, but Adele smiles and realizes he was telling the truth all along. She calls her superior, who asks how the execution went, and she says, "I've got a better story. It's a love story..."
The ending of "Do Not Open This Box". Ruth's soul is taken instead of Charlie's, and Charlie's invention is useful to the mailman (thus fulfilling his dream of inventing something helpful). Although it's somewhat bittersweet that the mailman, only friend Charlie's ever made in 35 years, has to leave, something better comes along. Clarissa Sanderson, who Ruth has a one-sided rivalry with, visits Charlie. It's implied that she and Charlie begin a relationship after their visit. All in all, after years of humbly putting up with Ruth's verbal abuse, Charlie earns one big Earn Your Happy Ending.
The ending to "Distant Signals". Even if the show was unpopular on Earth, "Max Paradise" is beloved and popular on a distant planet, where they'll be happy to know the series has been given a proper conclusion. In fact, the last shot of the episode is of Van and the show's director discussing the prospect of it all.
At one point, Van's alcoholism gets the worse the him, making him decide to abandon the revival. Smith, in turn, heads over to his apartment and actually removes his alcoholism, giving him the clear head needed to continue.
The ending of "Trick or Treat". Billy, whose father doesn't want him to put him through a cruel Halloween game that will pay off their debts, goes anyway without his parents knowing. Since Mr. Hackles is out of the way, the Witch answers the door instead. What she does next is surprisingly nice on her part. For his good karma, she gives Billy his father's IOUs, the whole town's IOUs, and then some from Mr. Hackle's treasury before flying off on her broom. Billy smiles at seeing a live witch, and a generous one at that. If there ever were such thing as a Halloween Miracle, this was it.
