Was this before he was fired or just realised that he wasn't actually up to the job?
He was
**** canned...but he went out like a gentleman. That's where the conversation goes like this:
Luca: Do I have to say the words, Stephano?
Stephano: I'm fired?
Luca: Fired? I only wish we were in the army, so I could have you shot.
Stephano: OK. Do I get a severance?
Luca: Sure. You resign, blame yourself, support the team and you get one. You don't, you'll be at the bottom of the Mediterranean wearing concrete loafers within the hour.
