Finishing Each Other's Sentences

"Edward: You're the fairest maid I've ever met,

You were made--

Giselle: To finish your duet!"

- Enchanted

"This finishing each other's sentences thing is freaking me out!"

- Ron Stoppable

We've all heard it before... literally. Some people know each other so well, they finish each other's sentences. The effect is usually a demonstration of how close the two people are-- they're so familiar with one another, they even think alike.

Generally comes in two forms-- the single line and the complex dialogue. The single line goes something like, "Bob: Where are my damn--

Alice: Glasses? Check your head."

The complex dialogue is more elaborate: "Bob: Where are my damn--

Alice: Glasses? Did you check your--

Bob: Yes, my head is always the first place I look, thank you very much.

Alice: Mom was right, I should never have married--

Bob: "A forgetful lout like you," yeah, I know."

Closeness and familiarity aren't the only reason for this trope. Others include:

"Alice: This looks like a job for--
 * Lampshading a Catch Phrase or Arc Words

Bob: Someone else."

"Alice: Superman will--
 * Mocking someone for their clichéd ideas:

Bob: Rescue you? I think not."

"Alice: That sexy young farmer has an enormous--
 * Last-Second Word Swap (especially when the audience was expecting it to rhyme):

Bob: Potato gun!"

"Alice: Maybe we should--
 * Making a quick gag by having the finished sentence be nothing at all like what the first person was going to say.

Bob: Tie a banana on its nose and conga under its legs!

Alice: I was going to say call the police."

"Alice: Maybe we should--
 * Showing that two people who don't know each other are thinking the same thing.

Bob: Cross the streams--

Alice: And reverse the polarity--

Bob: To raise the deflector shields! Marry me."


 * And more!

This trait is often found in Creepy Twins, Single-Minded Twins, and Sickeningly Sweethearts, but hardly restricted to them-- lovers, parents, siblings, friends, co-workers, enemies, even strangers can do this. And while we're at it, it doesn't have to be only two-- loads of people can get in on the act, although it might start to stretch credibility. Also present as a way of showing that two characters are telepathic or are parts of a Hive Mind.

If the characters are built around this trope, it's a sign of a big problem when they don't finish each other's sentences. If one character is a psychic, expect the other to shout something like, "Get out of my head!" Or even if they aren't psychic, if it happens often enough.

A similar effect is having characters Finish Dialogue in Unison. Two Scenes, One Dialogue and Distant Duet have characters finishing each other's sentences without even being in the same scene. Compare Strange Minds Think Alike, Catchphrase Interruptus.

Anime and Manga

 * The twins Hikaru and Kaoru in Ouran High School Host Club do this sometimes. In Haruhi's Alice in Wonderland dream, they played the Cheshire Cat and appeared alternatingly from different sides, finishing each other's sentences as they talked to Haruhi.
 * Happens in the finale of Stellvia of the Universe between Richard James and Carl Hutter when the two are having a few drinks on a desolate space station deck. James raises a toast, starting with "To the future...", and Hutter completes the sentence instantly, in the same tone: "...of humanity!" This is especially poignant, considering how.
 * While not the most typical example of twins, in Cardcaptor Sakura, Yue and Cerberus pick a climactic moment during the final judgment to suddenly start finishing each other's sentences--with multiple clauses, no less. In fact, despite their apparent hostility toward each other at the time, it becomes nearly impossible to distinguish exactly who is speaking at some points.
 * Gunslinger Girl. Cyborg technician Louis Duvalier has beautiful twin assistants who do this. They even move in unison.
 * Koizumi and Otani from Lovely Complex are so (unintentionally) good at this that they (again, unintentionally) become a comedy sensation at their school.

Comics

 * In the Scott Pilgrim books, Ken and Kyle Katayanagi often finish each other's sentences with their reasoning behind it being that they would always work together after Ramona cheated on them behind their backs. This was obviously not in the movie as the only line the Twins have in the film is "Hah!" during a fight sequence.

Fanfic

 * The Weasley Twins, from Harry Potter are not an example, even though they are popularly portrayed that way in Fan Fiction. They don't complete each other's sentences in the books; rather, one will follow the other with the next appropriate sentence - they do not share a single mind, but simply think very much alike.
 * The ideal is Lampshaded in Harry Potter and The Methods of Rationality, which features a sections focusing on the Twins, and indicating something magical is at work. They don't actually share one mind, but come to the same conclusions when they have the same information. When one of them thinks differently than the other, they both feel uncomfortable until they share what they know and snap back.

Film--Animation

 * The Fates from Disney's Hercules do this, most noticeably in their introduction, when they're giving Hades the prophecy.
 * Tweedle Dum and Tweedle Dee in Disney's Alice in Wonderland (but not in the original book).

Film--Live Action

 * From Scary Movie 4:

Tom Ryan: ...common.

Cindy: We're already finishing each other's...

Tom: ...dinner!

Cindy: ...sentences."

"Field Marshal Von Kluck: We were able to dupe Dr. Forrest by posing as a humanitary organization, who planned to wipe out hunger, by ageing cheese faster.
 * The twins from Snatch do this.
 * In Stuart Little, Mr. and Mrs. Little do this so frequently that they panic when they don't. Stuart cutely lampshades this as he hears his future adoptive parents do this for the first time.
 * From Dead Men Don't Wear Plaid:

Rigby Reardon: But when your father finally saw what they were doing...

Field Marshal Von Kluck: - he began to assemble lists of names of our agents...

Rigby Reardon: - and seemed about to go to the FBI.

Field Marshal Von Kluck: We were zerfore obliged to kidnap him, drug him ang bring him...

Rigby Reardon: - here! First faking his death so there'd be no further investigation.

Field Marshal Von Kluck: But vile testing ze mold on a small island nearby...

Rigby Reardon: - the cruise ship "Immer Essen" passed by. Some of the passengers saw the tiny island dissolve.

Field Marshal Von Kluck: Zey were zerfore labeled "enemies" because of what zey haf seen. We had Walter Neff cancel all further tours and our...

Rigby Reardon, Field Marshal Von Kluck: - friends systematically began to eliminate everyone who was on that cruise ship.

Field Marshal Von Kluck: Schweinehund!

Rigby Reardon: Jerk!"

Literature
"You finish each other's sentences half the time -- or sometimes, if you think no one else is listening, you don't bother to finish them because you both know what you were going to say."
 * Robert A. Heinlein's Lapis Lazuli Long and Lorelei Lee Long are clone sisters who do this. They first appear in his novel Time Enough for Love and show up in his later novels.

 * Harry and Hermione do this sometimes in Harry Potter, such as in Deathly Hallows when they discover what happened to.
 * In Fanon, Single-Minded Twins Fred and George Weasley are often written as doing this. In the books it only happened a couple of times and was more like collaborative interrupting. The movies were much more guilty of playing this trope straight with them.

 * A variant in the Starcraft novel Liberty's Crusade. Kerrigan, being a telepath, tends to finish other people's sentences out of habit, which annoys just about everyone else. When she's leaving for her totally-not-a-date with Raynor after the Antiga mission, Liberty's last bit of advice is "remember to let him finish his damn sentences".
 * In The Hunger Games, Wiress tends to trail off or just stop speaking abruptly in the middle of her sentences, at which point Beetee finishes them.
 * In Spindle's End by Robin McKinley, Rosie and her best friend Peony take this one step further.

""We're thinking of writing a book, aren't we, Merv? All about how we..."
 * Lampshaded in Artemis Fowl and the Opal Deception. Mervall and Descant are twins, which are very rare among fairies.

"Finish each other's sentences," completed Merv, though he knew it would cost him.

"Shut up, you utter imbecile," snapped Opal, shooting Merv a poisonous glare."


 * Reynolds and Claude's promotion interview in the penultimate chapter of The Pale King.  incredulously wonders how long they had to practice it.

Second man: --oo--

Third man: --d

First man: ev--

Second man: --eni--

Third man: --ng."

"Michael: It's like we finish each others'-

Michael: That time I was going to say "sandwiches"."

"Brian: "I'm not being cynical, I'm being-"
 * In Broken News, the newscasters for PVS News routinely complete each others' sentences, or even words.

Brian: "Do you mind if I finish my own sentences? I despise when couples do that.""

"Rory: Gary and I have been working together for so long that we can actually...
 * Sheridan and Delenn in Babylon 5 do this a little.

 * NCIS Los Angeles has Nell annoying the hell out of everyone by doing this on her first episode. Characterization Marches On, though, and now she's just doing it to Eric. It's played for laughs, and incredibly cute. Other partners on the show tend to do this as well.
 * All over the place on NCIS. McGee/Abby, any partners, any time the field agents brief Gibbs, any time Gibbs gives orders and the others anticipate him . ..
 * Gem and Gemma from Power Rangers RPM do this habitually; they don't speak (or think) as individuals much if at all until Gemma gets a boyfriend. After that, while they show signs of not being a Hive Mind, but still do this frequently. Just not all the time.
 * Kirk and Spock do this occasionally in Star Trek the Original Series.
 * In Star Trek the Next Generation there is a whole race known as the Binars who talk this way because of their binary/pair based culture and biology.

Teyla: Feelings?

Sheppard: Yeah, sure, okay. The point is, I don't really have good, uh...

Teyla: Social skills?

Sheppard: Well, that is why I enjoyed flying choppers in the most remote part of my world before all this craziness happened, but, uh, you should know, I don't have, uh...

Sentence Finisher: Uncanny accuracy?"

Stand-up Comedy

 * This is a crucial part of the stand-up act of Randy and Jason Sklar, as they are identical twins with exactly the same voice who seem to run on the exact same wavelength at all times. They practically turn finishing each other's sentences into a zen artform.

Theatre
"Suffolk: Great men oft die by vile bezonians:
 * One performance of Henry VI Part II has Suffolk dragged offstage and killed before delivering his last line, leaving it to be completed by the pirate captain, which adds a wonderful creepiness to the scene.

A Roman sworder and banditto slave

Murther'd sweet Tully; Brutus' bastard hand

Stabb'd Julius Caesar; savage islanders

Pompey the Great; and Suffolk--

(sound of an axe)

Pirate: Dies by pirates."

"Hotspur: ...O, I could Prophesie,

"Replying, we sing
 * In The Gondoliers by Gilbert and Sullivan, when Marco and Giuseppe agree to jointly become the King of Barataria, they announce this in a verse where each of them sings only every other bar. It works like this, with Marco's part in plain text and Giuseppe's in boldface:

As one individual,

As I find I'm a King,

To my kingdom I bid you all.

I'm aware you object

To pavilions and palaces,

But you'll find I respect

Your Republican fallacies."

Webcomics

 * This comic from Saturday Morning Breakfast Cereal. It gets worse very quickly.
 * Tina of Wapsi Square does this to just about everyone, though she has been wrong at least twice. However, on both of those occasions, the question that was actually being asked was not one that she necessarily wanted to answer, so it may have been intentional. She also predicts the orders of everyone who comes to her coffee shop.
