In the scene where Hermione, Ron, and Harry are taken to meet Grawp by Hagrid, Grawp picks up Hermione and then sets her down when she orders him to do so. He then walks over to his pile of things and brings her an unattached bike handle with a bell on it. However, after she rings it for Grawp, the next scene shows him with the handle and bell again as he sets down to play with it himself. Yet we never see Hermione give the gift back to Grawp!
