So now we know that all seven compete. We know that three move on. We know the three are Albert, Rick, Sophie.

Because the Press Pics specify IC/RC, we know that the winner wins reward.

We are left to solve:
At the immunity challenge, one tribemate makes a big gesture to a fellow castaway.

What is left?
Giving up reward is the most obvious answer. That would be a huge sacrifice.

However, it doesn't say "sacrifice"; it says "gesture."
A gesture can be an act of kindness towards someone who doesn't expect it.

The contenders for winner are all Stargazer Allies. It would not be a special gesture to pick another SA. That leaves Cochran or Edna.

I see two possibilities there IF this were the gesture.
1) Rick wins and takes Edna. They are close. This would upset Albert at Rick. Rick would likely take Coach and Edna.

2) Albert wins and chooses Cochran. This would set the stage for Albert and Cochran scheming together to take out Rick. Albert might take Sophie and Cochran. Rick would feel left out, as he was a top contender.

If Sophie wins, I do not see her taking a non-ally, not even to cultivate a juror, because she doesn't think much of either Cochran or Edna. I think she would take Albert, because she needs to keep an eye on him. For a third she would likely take Coach, to reassure him.

I think that three will enjoy the reward.
ETA:

ETA -- I realize that picking anyone to go on reward is not necessarily a BIG gesture, unless the recipient is feeling ostracized. Picking Cochran could be a big gesture, since he always feels that way. Edna wouldn't.

It would certainly be bigger if someone gives up reward for someone else. For example, someone is picked, and he says, I really want to go, but so and so needs it more.

We rarely see any selflessness at these reward choices unless Jeff proposes it first. So how would Jeff suggest it? Per the clue, this is a gesture from one person to another. It is not like one person giving up for the tribal good.

In Nicaragua, with the volcano reward, Jeff gave the guys a chance to let one or more of the girls go. Was that a one person gives it up for another offer?
