Hannibal - What Might Season 4 Involve?

While negotiations still remain rather tight-lipped at the moment on a potential 4th Season for Hannibal that hasn't stopped Den of the Geek from posting an interesting speculative piece about what the future of Hannibal might look like based on how things concluded at the end of Season 3. Will we see the further corruption of Will Graeme? Will Clarice Starling make an appearance? Will they bring down Hannibal together? No one knows but it's fun to speculate! I've attached the article as it makes for an interesting read to any Fannibal wondering the same thing. What do you guys think Season 4, if renewed, would be about?
