In the scene in Edoras where Pippin takes the Palantir from the sleeping Gandalf, he replaces the Palantir with a stoneware jug (so Gandalf is now clutching the jug instead of the seeing stone). When Pippin is reacting violently to his vision in the stone, Merry cries out in fear to Gandalf, who wakes up and jumps out of the bed, sans jug. What happened to the jug??
