What happened to the apple that Emma gave Jacob?

The apple that Emma gave Jacob rotted.

I slipped a note under his door and went to grab Emma’s apple, but it wasn’t on my nightstand where I’d left it. A thorough search of the floor uncovered a lot of dust bunnies and one leathery thing the size of a golf ball. I was starting to wonder if someone had swiped it when I realized that the leathery thing was the apple.
