never ever introduce a new idea at the end of a story. it’s the end, you don’t want to restart.
One great example of suspense in the Hobbit is when Bilbo is in Smaug's smoky, gold encrusted lair, trying to find the sparkling cup, without awakening the dragon. A few times, we see the dragon release a puff of smoke, or stir, and Bilbo stops abruptly, than tiptoes forward quietly. There is so much suspense here while we await his fate!!
"This is the second activity in the repetition strategy" indicates that the word revisit would be the best word to use to sum up the idea since repetition strategy definitely suggests revisiting. Something which is repeated is done over again so in the act of re-doing it it means it is also re-visited.
