#1 What to expect when you're expecting.. Snape to be the bad guy

Having read the series countless times, it's hard to find myself surprised by the outcome of the beloved stories, though this does not keep me from loving the books more and more every time I do read them.  Having said this, I do have to agree with Iser’s argument that most books do not turn out the way you may think. 
I can clearly recall sitting in my bed at night fighting to stay awake, trying to convince my mother I wasn’t tired and to read me just one more chapter.  This was because back then, my first time experiencing the books, I thought I knew everything. I was only seven years old when Sorcerer’s Stone was published in the US and while I thought I was extremely clever, I couldn’t have been more wrong in my prediction.  Naturally, I fell for Rowling’s ruse that Severus Snape, with dark eyes and greasy hair, was clearly out to get Harry and was most certainly trying to sneak past Fluffy.  
Well turns out, seven year old Jenna was very wrong and Snape turned out to actually be trying to help Harry!  While this was a blow to my seven years strong self-esteem, it only reinforces what Iser says about expectations and how they can be unfulfilled.  And although I was not pleased at being duped by JK Rowling, it was a very smart thing for her to do.  Not only has she shed more light on Snape’s character by doing this, she shows the reader that overcoming evil isn’t going to get any easier for Harry.
