Common Plot Errors: The Rug Jerk

The "rug jerk"1 ending is one that doesn't follow the story's internal logic, and leaves the reader feeling like they've just had the rug jerked out from under their feet. It is, in short, a surprise ending that's too surprising.

The key difference between a rug jerk ending and a surprise twist ending is that on reflection or a second reading, the rug jerk still doesn't make sense.


Writing a rug jerk ending can be seen as an author over-compensating to avoid a predictable ending. It's a rare author who's happy with an ending that was obvious in every detail from the beginning, so most try to put in some kind of twist. A good twist isn't the easiest thing to create, either. A rug jerk, on the other hand, is much easier to come up with because it doesn't have to fit with anything that came before.

It isn't something readers like though. It's disorienting, unsatisfying, frustrating, and fortunately doesn't usually make it through the publishing process. It also betrays the trust that the reader gave you - to tell a tale that is true to its own logic all the way through. Even seeming exceptions to the rule often aren't: for example, the Hitchhiker's Guide to the Galaxy has an internal logic that says that if it's absurd, improbable, and completely ridiculous, it'll probably happen. The discworld series follows the rule that "million-to-one chances happen nine times out of ten." They are true to their own structure.

Fortunately, a rug jerk is fairly easy to spot. Just read the whole story, and if you can't explain the ending in terms of the story logic, it probably needs to be fixed.

The rug jerk is somewhat related to the Deus Ex Machina as they share a complete lack of foreshadowing. Instead of a previously unmentioned  talent, object, or person suddenly appearing to save the day, a rug jerk uses an event that wasn't set up or even hinted at earlier in the story to change everything. Sometimes, if the author is aware on some level of how disjointed the rug jerk is, a character will express that by commenting on how unbelievable it is - but that's a symptom, not a fix. ("I wouldn't believe it myself if I hadn't seen it!" won't make the reader believe it...) Remember, just because life doesn't make sense doesn't mean a story doesn't have to.

Fixing a rug jerk is easy to summarize, but not as easy to actually do - and it depends a lot on both the story and the author.

If you're convinced that the ending must stay, then you'll want to go through your story and plant hints throughout, so that the ending can be explained by the story logic. If you're willing to change the ending, then you'll want to go through your story looking for hints that, when taken together, suggest an ending. You may find some excellent foreshadowing already there - like themes, a pattern of hints has a way of sneaking into a story without you noticing at the time.

Or you could do a combination of both - see what endings suggest themselves and add hints as necessary to support the one you choose.

Just remember not to take the first idea you have without looking at a few others too - usually the first idea to show up is the obvious (and predictable) one, and obvious and predictable is what you were trying to avoid in the first place!

1. Credit where credit is due... I didn't come up with the term "rug jerk" for this plot error. I first read it in the turkey city lexicon, a very entertaining and entirely correct list of common plot, characterization, and setting errors. It's written for SF, but many of the items are applicable to all genres.

surprise endings (5.00/1) (#1)

you are right about authors being unsatisfied with predictable endings, and thus the frequent occurence of the final act plot twist or "surprise ending". but i think that you are too gentle on surprise endings in general.

certainly, it is reprehensible when the author is so desperate to surprise the reader that, in the last few pages, he abuses his power to introduce a miracle or previously unmentioned story-resolving character, thus destroying the delicate world he had created in the reader's mind. but i find it just as bad when, as in the more traditional surprise ending, the writer finds himself depending largely upon the withholding of information from the reader to create suspense.

the ideal twist ending should be unpredictable but, once read, seem inevitable. it should be an artful application of the butterfly-hurricane principle with the reader getting that rare glimpse of the usually unknowable path from one to the next.

i think perhaps the best surprise ending i can quickly bring to mind is that of Romeo and Juliet. To a theoretical person who did not know how the play ended, the final scene would be very difficult to predict. it is truly a surprise ending. yet, no cavalry rides over the hill. the lynchpin upon which it all hangs consists of just two miniscule events: the failure of Friar Laurence's note to reach Romeo and the tragic timing of his entry to Juliet's tomb. Given these two events, the play can only end in one way.

if a book has a good ending (whether twisty or straight), the knowledge of that ending should not dampen the enjoyment of the rest of the book. and this is so for Romeo and Juliet, for very few people are, like the theoretical reader, ignorant of the way the play climaxes, and yet it continues to be enjoyed.

in fact, it has long been a practise of mine to, when i am uncertain about whether i care to finish a book i am reading, i will flip to the end and read the last chapter. if it is a poor novel, then i will feel that i know all i need to know and will be happy to set the book down. if it is a good novel, then i will find my interest newly piqued and want to read the middle sections to understand just how the narrative reached this final stage.

and, most importantly, i have found that this is a very useful tool to improve my own writing. whenever i am composing a story, i always try to imagine some prospective reader who reads the last chapter first (or the last few paragraphs for a short story) and, if i cannot foresee this reader then bothering with the rest of the work, well, i am cheating not just him, but all my readers.

Yes, exactly!

This is why I was talking about scattering hints (or looking for hints that snuck in) when working on the ending. The clues should be there, so there's no witholding of information, but they should be small and not obvious except in hindsight.

The Punch in the Gut (5.00/1) (#4)

All Quiet on the Western Front has a surprise ending that one might take to be a rug jerk, but really is not. I won't tell you because I don't want to ruin the experience of reading it for yourself, but I will tell you that I read it thirty-six years ago, yet it still fills me with despair even to mention it now.

Not despair at having read a poorly written book: it is one of the best books I have read. There have been I think two movies made of it. I've seen the modern one and feel it is excellent too.

No, despair at the fact that there ever has been such an evil thing as war, and that we are still faced with it. There are very few pages in the book that fail to express war's evil nature, yet it is the surprise ending on the book's last page that, in my view, espresses that fact most forcefully and eloquently.

It is not a rug jerk for other reasons, in that it is consistent with the logic of the rest of the book. It could have ended without this final twist and possibly remained a best seller, but not as memorable a one.

Even Stephen King is guilty (4.00/1) (#3)

My wife Bonita is a great fan of Stephen King, and long has encouraged me to read him. I recently read On Writing and recommend it to everyone. But Bonita tells me that King's It was one of the worst books she ever read:

She found the story gripping until a few pages from the end, when it turns out that the evil clown who terrorized everyone was in reality a giant space spider. She said it was as if King got up from his desk to use the restroom, and upon returning forgot what he meant to write about.

Myself, I think it was some kind of contractual dispute.

I'm pleased to find the above article after returning to Write-On after so long away. I'm working on an essay I will submit in a day or so that uses It to demonstrate that even the best writers still struggle with their writing. When I do, I'm going to make the words "giant space spider" a link to this page.
