Since there was that picture of Eddie Izzard filming for S2 of Hannibal maybe he’s going to help Will out.
They might have nearby cells and Gideon might start telling Will what actually happened when he had his seizure because he’s pissed off that Hannibal set him up!
Idk or it could just be a flashback or something…
but either way,
MORE EDDIE IZZARD!
