Book Ends

-we came in?

Matching scenes at the beginning and end of a story, often to show how things have changed through the course of the episode, or to demonstrate that they haven't changed at all.

This is extensively used in kid's shows to illustrate the characters applying the lesson they learned today, which happens to apply to the issue presented in the beginning. Ya'know, just in case they didn't catch it. In any work, bookends are a way to show whether Character Development has occurred.

Compare and contrast Here We Go Again, How We Got Here, Where It All Began. See also Call Back, Ironic Echo.

Bookends don't always spoil the ending, but usually they do.

Advertising

 * The Montana Meth Project has some chilling public service announcements, with these two having the Book Ends. The first video shows a girl trying meth with her friends, saying she's only going to do it once. Cut to the next scene, where she uses meth again, still saying it's only once more. This was repeated a few more times, with the girl getting worse by the use of meth. At the end, the girl dies on her bed. Her younger sister then takes some meth from her older sister's jean pocket, saying she's only going to do it once.
 * The next video shows a young man trying meth, also saying that he'll only do it once, as he doesn't want to be like 'That guy', a meth-addicted psycho, which scarily resembles him. He then tries meth once again, also with the same promise. Repeat a few times with the man getting more addicted, and he ends up being exactly like 'That guy'. In the end, a young girl buys some meth with the promise of only trying it once, as she doesn't want to be like 'That guy'. Which is obviously the guy before.
 * In a similar vein, an Australian alcohol awareness advertisement opened with a father asking his son to get him a beer at a party, followed the son's descent into alcoholism, then ended with the son as an adult, asking his son to get him a beer at a party, with the implication that his son's life would follow the same course as his own.

Fan Works

 * The Star Trek: New Voyages episode "World Enough And Time" has beginning and ending scenes that take place about 30 years from the time of most of the episode, all based around the character Hikaru Sulu.
 * The Harry Potter Fanfic After the End begins and ends with a group hug surrounding Harry. Everyone is in a dark room, lit by a bluebell flame, which someone kicks out.

 * Two in With Strings Attached:
 * At the very beginning of the First Movement, Paul and John nervously walk along the beach, completely new to the world, wary of each other, and frightened. At the end of the Second Movement (in the chapter “Full Circle, Moebius-Style”), they walk together along another beach, back to being friends, more or less accustomed to the world (if not to their new magic), and enjoying sharing this utterly unique experience.
 * When the four first arrive in Ta'akan, they have a frightening experience in the Owner's Head Tavern when an enormous Bar Brawl erupts around them. When they leave the city for the last time (not counting when Ringo accidentally teleports back there), they have dinner in the Owner's Head and laugh at how tame the nightly brawl seems now.

Mythology

 * Older Than Dirt: The Epic of Gilgamesh starts with a narration that extols the might of the walls of Uruk, which seem to be meant to emphasize the glory of their builder, the king Gilgamesh. Until, of course, Gilgamesh fails to gain eternal life, and in the final line of the epic, he speaks the same passage to his new traveling companion Urshanabi. (Scholarly opinion is divided whether this is intended as Ironic Echo, or an affirmation that true immortality is found in lasting greatness of a man's works.)
 * The Hebraic multilingual poetic device called a chiasmus is this trope defined.

Poetry
"There are strange things done in the midnight sun by the men that toil for gold The Arctic trails have their secret tales that would make your blood run cold The Northern Lights have seen queer sights, but the queerest they ever did see Was that night on the marge of Lake Labarge that I cremated Sam McGee"
 * "The Cremation of Sam McGee" by Robert Service both begins and ends with the same stanza, referring to the queerest sight ever seen by the Northern Lights (namely the eponymous cremation). The poem in between these stanza's describes the events of Sam's death, his subsequent cremation, and what the narrator saw when he looked into Sam's funeral pyre..

"'Twas brillig, and the slithy toves Did gyre and gimble in the wabe, All mimsy were the borogroves, And the mome raths outgrabe."
 * Jabberwocky (largely nonsense):

 * This happens again in the Recollection Saga. Reconstruction began with a soldier looking at the dead body of a Freelancer as the camera panned up in Valhalla, showing a huge number of characters (so many that the creators actually had to run several games and use splitscreen to get that many). Revelation ends with a soldier looking at the body of  in Avalanche and the camera pans up to show a similar shot.
