I'm certain that you're right, Outsider: Jeff Probst will always "decide how he wants it". But, for the record, four years ago, Andy Dehnart at Reality Blurred published a copy of a Survivor's contract that contained a set of its 'Rules'. And below is the excerpt relevant to Voting/Ties.

Whether or not those 'Rules' are still (or, at a producer's discretion, ever were) of any practical value is, I think, anyone's guess.

Kass/Woo/Trish-Spencer
Tasha/Spencer/Tony-Kass

I think that I've asked the wrong question. Or, perhaps, not the important one: 'Who do you see as the targets in a tie (3 - 3) scenario?'.

Because, if one of them is Tony, the moment he plays either of his Idols, the tie no longer exists. And I can't think of any rational reason why he would not just kick back until after the votes are read and then play his first - 'Super' - one. If necessary. This week. Or next. Or whenever.

But, even if he does manage to escape the trap of attempting to bribe happiness with an Idol, they will run out. And Tony is not a Challenge threat. Nor has he been good, or bad, enough for anyone to offer him a gratuitous seat in the Final Two.

Note: Among Sagittarius’ less attractive traits are social insecurity, shallow emotional responses and addiction to attention. Giving, if you will, DAW – when applied to a native - a whole new level of meaning …

So, I am extremely curious to see if, before the end of a tough 39 days, Tony managed to put them behind him and enjoy Cagayan’s Final Tribal Council.

I hope so. Because, while Spencer may have made the Season – strategically - interesting, Tony made it – competitively – fun.
