They give Sam a comic book about vampires, and insist he keep it with him.Sometime afterward, Sam begins to notice his brother Michael acting strangely. Sam is also surprised when his Mom's boss' dog almost attacks her, in a way just like out of the comic the Frog Brothers have given him. Though it is recommended that he kill Michael, Sam is unwilling to do so to his own brother. Sam then suggests that Michael may only be half-vampire, and if they can kill the head-vampire, his Brother will be returned to normal.
