Alan Grant followed as Chance Silvey, normally focused and as sharp as a tack, lead him through the twisting corridors of Hogwarts. She was searching for someone, or something. He wasn't quite sure which. But along the way he's been piecing together what she's been saying, and the writing on the wall.
Dicranurus monstrosus. A trilobite.
He was mentally kicking himself for not identifying it sooner, but invertebrates had never held his interest. She'd mentioned evil trilobites when he'd first met her, and how she knew about them, but didn't, somehow. The whole conversation had been confusing, and they'd made jokes about geometry and the strangeness of her sorting, and eventually he'd forgotten the whole thing. It wasn't a bondo bug in his office, it was an honest to God, should have been dead as a doornail trilobite sitting in a tank next to his desk.
They passed a familiar hallway and Grant stopped Chance. "Wait just a second, Chance, okay?" On second thought, he was worried to leave her alone. She probably wouldn't be there when he got back. So he took her with him up to Gryffindor, where the door was propped open, like most of the dorms. it was sheer luck that Billy Brennan was hanging out in the common room.
Billy saw Chance holding Grant's hand and the worried look on Grant's face, and blurted out, "I don't want anything to do with this."
Grant rolled his eyes. "Shut up and come with us," he said. He gently shook Chance's hand free and whispered to Billy, "Something's wrong with Dr. Silvey. I need to know where you found that bug."
Billy looked from one person to another. "Sure," he said, licking his lips nervously. As he got up, he whispered back, "What the hell is going on?"
"I have no idea," Grant replied. He turned to Chance. "Billy's going to help us find Dancy, Chance. Is that okay with you?"
