In this passage, O'Brien varies from short, choppy sentences to longer, more in-depth sentences, uses repetition, and provides unique punctuation.
Out of the first eight sentences in the passage, six of them contain eight words or less. Then, the last two sentences both have at least twenty seven words. The mix of sentence length makes this passage eye-catching. The short sentences make the paragraph easy to read while the longer ones' purpose is to add character thoughts, which makes the passage easier to understand.
The theme of repetition is present in the passage and it adds stress to the reused words. "Because there was always the threat of tomorrow's treachery, or next year's treachery, or the treachery implicit in all the tomorrows beyond that" (43). The repetition of treachery makes the sentence feel gloomy and sad and that if Kathy ever did something to break John's trust it would hurt John greatly.
What also makes O'Brien unique is his use of punctuation. "Required the certainty of a confirmed betrayal; a witnessed kiss, a witnessed embrace" (43). Instead of separating the sequence with periods, O'Brien uses a semicolon and uses a comma at the end of the sequence. The semicolon makes the reader stop for a second, which isolates the next part of the sentence and makes it stronger.
