Hannibal tells Jack he’s overworking Will, making him doubt his judgement, and tells Will that Jack’s overworking him, making him doubt Jack. Will asks Hannibal if he’s alienating him from Jack and he was right. Hannibal does the devil’s work in slowly and nauseatingly removing them from each other throughout season 1, and so when Jack tells Will that he is not sand for Will’s moorings, rather he is his bedrock, it is heartbreaking to see where they end up in s1e13. Jack tells Hannibal that he believes that Will would always come back to himself, and that was true. Hannibal was only able to break Will from psychic driving and encephalitis and EVEN THEN Will managed to reclaim himself, just like Jack prophecised, unlike Miriam Lass. And Jack knows what Hannibal offers to Will intellectually, so when Will tells him he wanted to run away with Hannibal, there is shock, but when Will later tells him “A part of me will always want to run away with him” in Florence, there’s understanding. He has to tell Will to cut that part out of himself though, because even though Will yearns for Hannibal, Hannibal is the Chesapeake ripper. He is a monster. And Jack needs Will to put a full stop to this thing Jack started. Jack dragged Will into this, and when Will asks why he didn’t kill Hannibal, he says “I needed you to do it.” And there is so much regret and heartbreak in his words. The relationship between Will and Jack is so tender to me as it grows and evolves throughout the show. I would have loved to see what he’d have done after Will and Hannibal eloped in season 4 💔
