I agree. I think Vic was going to announce his departure anyway. Then they offer him money to do so, and he smiles as he drops the ring... thinking he just came away with $10 G that he otherwise wouldn't have had.Of course, the producers probably were aware of his intentions, and arranged the money payout to add drama (and reason) to his leaving. Not a bad idea on their part.
I also thought he told Erica with a reasonable amount of class.

Contradictions don't exist. If you are faced with a contradiction, check your premises. You will find that one of them is wrong. -- Ayn Rand, Atlas Shrugged
