Pickles the drummer.

You were Charles's sister. The people from Dethklok knew nothing about them, but you did, since Charles had told you about them, though not much, of course. One day you went to see Charles about something important, but the guards—or what?—were strange, with their faces covered by black cloths. You assume that's what they were. They stopped you and almost killed you until you showed them you were Charles's sister, at which point they let you in. When you went inside Dethklok's house, you didn't see your brother. You only saw Pickles drinking and doing drugs, calmly by himself. You went to him and asked about Charles. He didn't even bother to look at you, saying, "We didn't see Charles today. Are you his wife or something? Besides, how the hell did you get in here?"
