I hope the title is not misleading, anyway, the problem that I have (Or think I have) is the main character changing from a person into something of a beast. How can I slowly show what is happening without it being too sudden. How many words would you use for the character realizing what is happening? What would make it seem gradient? For me it feels like it is too fast. The MC returned from the expedition that had this effect on him, left home to resign being an assassin, went to a restaurant and realized that he was hungry for the blood of the waiter. He then Screamed with the strange realization and I am still writing it.
