Bill came charging towards the group (though he could hear them before he could see them), he had been planning to go after Oliver himself, but he had seen a group forming in Angelina's journal. Of course, he didn't think it was a great idea that Angelina go out in the woods with out her wand, but he knew there was no talking her out of it. Instead of trying, he simply grabbed the knife from out of his trunk (it was a decorative knife that he had gotten in Eygpt) and charmed the edges so that it would be sharp enough to use.
"We have no time to argue about it." Bill said with a pointed look towards Angelina and Percy. He didn't like that they were going out without a plan, but they had to find Oliver. Merlin, was he going to kill Oliver when they found him. "Try to stick together, at the very least we'll outnumber them." He said slowly before handing Angelina the knife.
