When Howard #4 lands in the girl's room, he picks up a cell phone that is already in the room. But, when he calls Howard #1, he gets his own voicemail, because the story incorrectly assumes that Howard #4 is dialing his own phone, and Howard #1 is too busy putting Molly #1 in the box. Also, the 2nd call Howard #4 makes on the call, James #2 answers it "Howard," because he has established that it is Howard from the Caller ID. But, how did the phone get in the girl's room before Howard #4's jump in there?
