Toothache?
Did they have cut scene where Sean/Caster had a toothache in solitary? You have the cutting between Caster/Sean basking in the glory of disarming the bomb and Sean/Caster in solitary holding a hand to his cheek looking like he's in pain ( to demonstrate his despair). Me thinks they cut a scene demonstrating he had a toothache but used those scenes to jump cut between Caster/Sean's glory and Sean/Caster's hopelessness.
