Answer:
At the end of the story, Sue reveals that the leaf actually fell, but Behrman painted a leaf to keep Johnsy alive.
Step-by-step explanation:
From the book The Last Leaf, Johnsy is gravely ill with pneumonia and is in the hospital where she has no will to live and is willing to die.
Johnsy is counting the leaves on an ivy vine as they fall off and she concludes that when the last leaf falls, then she must die but Sue calls Behrman a painter and he paints an ivy leaf and because of that Johnsy is kept alive because she had something to look forward to, a will to live.
