Ok, Merry and Pippin are being held by the Uru-kai (s/p?) and Merry has a major wound on his eyebrow, with blood going about halfway down his face. When Merry and Pippin run into the forest, the wound is magically gone!!! But then, when Merry is about to be stepped on, it reappears, but on the other eyebrow. And then, magically, when the tree is holding Merry and Pippin, the wound is right back where it started!!!
