But before he could sleep, there was something he needed to do. Harry closed the blinds around his four-poster bed, then cast a Silencing Charm around it so no one could hear. Then, from out of his trunk he pulled out a small satchel and withdrew a small glass bottle full of and iridescent liquid that reminded Harry of bubbles. Sitting on his bed with his legs crossed, he unstopped the bottle. According to Griphook when the goblin offered him the potion, apparently the transformation was unpleasant. Harry hadn’t even asked for it but somehow the goblins all knew that he needed it for something he would do later on. Odd, but Harry figured with the kind of luck he had he could use all the help he could get.
