The narrative form is like the imperfect, except that, in strong roots, the ִי  vowel letter of the final syllable changes to a tseirei: וַיַּזְכֵּר. There also changes in the narrative forms of some special roots. In ל”ה roots, the ה is lost, the stress moves forward, and in a few cases the result is indistinguishable from the פָּעַל narrative form: וַיַּ֫עַל.When there is also a suffix, there are no reductions, so the narrative is again like the imperfect.
