JEFF PROBST:Great question.
Lets start with the elements.
Cambodia was and Im pretty sure, still is, hot.
Extremely hot on some days.
Not hot like Man, its really hot out today.
Hot as in Holy crap, thats the sun!
And its heading straight for us!
But the key to this season is the players.
They are, without compare, the most motivated group of players weve ever had.
They have to live up to the opportunity theyve been given.
Thats what you saw in this weeks immunity challenge.
We did that in this challenge, as we really wanted to see how long it could go.
I even had friends visiting who also participated in the challenge rehearsal.
Nobody came anywhere close to Joe and Keith.
Theyquadrupledthe time our rehearsal lasted.
I was in awe.
I could not believe how long it lasted.
And with their necks craned up it was extremely uncomfortable.
I cant say enough good things about this group of players.
This is the new example of how this game should be played.
Take us through being there when Joe collapsed during the immunity challenge and then everything that happened after that.
Okay, so you are already in my head that this challenge has gone way beyond anything we rehearsed.
Its now become a true showdown between two true challenge threats.
Joe who has dominated, and Keith, one of the only people who can truly challenge him.
I honestly thought,Joe is going to win again.When Joe dropped, it was completely out of nowhere.
There was no warning sign.
Joe didnt utter anything like Im feeling light-headed.
It was like one of those inflatable air dancers you see at car lots suddenly lost all its air.
It was so confusing that at first I wasnt sure what had happened.
It wasnt until I got to him that I saw he was out.
We called in medical, who is always just outside of the camera crew watching and waiting.
He knew exactly what had happened.
It literally just stopped responding to his will and he dropped.
As Dr. Joe said, he used up all of his energy supplies.
It was an amazing display of determination.
He literally went as far as his body could take him.
Heres another layer, Keith was not far behind.
Keith had also pushed his body way beyond anything it was used to.
Had they gone much longer, it might have been Keith who dropped.
Both guys should be in the Survivor Hall of Fame based simply on that performance alone.
Yes, I am!
I am going to make you pick!
Ah thats a very tough question.
I cant hide my emotion as easily as I did in the past.
I have to be honest and say that I am a big fan of love.
So I feel the love when Tashas cousin hugs her.
I can obviously feel the love of Kimmi saying Daddy.
But there were two big ones for me.
Yeah, imagine that.
I was just happy to see him so open with his love.
And the other big one was Jeremy.
If I had, I might have lost it.
That was pretty powerful.
Just two episodes left!
Tease us up for the big penultimate episode.
Next week is a pivotal episode.
Its do or die.
The vote here is critical.
You are deciding whom you will go toe to toe with in that final week.
Nobody is certain of the right move.
Plus, another scary situation and another Survivor in trouble.
