I thought everyone comes back as evil?
When Gus comes back, hes not an evil killing machine. Sure, he kills people but when he's in the house and sitting at the dinner table with drew and jeff, he starts laughing while mashed potatoes are falling out of his mouth.
Why wouldn't he just kill everyone if hes evil? What's with him laughing and walking around and fixing his wound in the bathroom?
Plus, he would just stumble around and wouldn't say a word. Wouldn't people be wondering why Gus was a mumbling zombie walking around like a clumsy fool?
Drew's mom acts like Gus is perfectly normal when he's sitting at the dinner table. Did Gus always just sit at the table making strange noises with mashed potatoes falling out of his mouth?
