Hassun is just Hannibal making sad cannibal noises and regretting all of his choices as he pines away for his little Graham cracker.
Do you think Hannibal can apologize to Will, or even to anybody, and mean it? I suppose the corresponding question is: Can Lucifer apologize? Can Alpha Males apologize? I would like to think that he is evolving in this regard, esp. after episode 2.13. Will has changed, has Hannibal also changed? It would be less obvious, but I hope so. What do you think?
