for anyone who wants to , their are ways to get hal to hesitate when speaking , I think someone mentioned it before and I have in the past it seems to me for making hal hesitate on purpose the best way is to emphasize a word ,
example :
the exorcist was a really "scary" movie , actually it still is !!
When hal says this sentence the word with the " " around it is emphasized and hal hesitates the word when speaking .
