Hannibal S1-S3

Something has been bothering me for a while now. I keep asking myself why Will Graham a good profile caught every other killer within a few days except Hannibal. But now I understand. Will deep down he had doubts About Hannibal but he was hesitant to look much into it , in the scene where Hannibal holds a feast for his opera club, Will was there when they were cooking and setting up the table. So when Hannibal invited him he declined and said he had something to do but you could see doubts in Will's face. I feel like Hannibal being his friend and backdoor psychiatrist he became somebody important to Will. In addition to Hannibal's questions like hey "did you enjoy killing Hobbs". this may have caused Will to entertain the idea of enjoying the feelings of the killers killings. Will has a lot of empathy, but with Hannibal he enjoyed the way his kills were done with purpose. It makes me feel like he liked being Hannibal's audience more than he could admit it himself.
