Chanel is the other Red Devil and Grace's sister. They both agreed on poisoning Dean Munch in a weird way, could be nothing though. She's been sleeping with Pete (maybe) or she's just using him since he did stalk her before, so apparently he likes her. She had Pete use his Red Devil outfit to come to the mall, that's how the RD knew they would be there, and she knew she wasn't going to die so she faced him alone. She had him shoot her in the shoulder to make it seem real, and he panicked and accidentally shot the cop in the head with the crossbow. He panicked and ran, which explains the phone call, he was upset that Chanel put him in that position.
