Some spec of mine on the family visit non-challenge:
In the pic below, we see that the word WHO most likely means "WHICH OF THESE FOUR" gets it, or as Jeff and Matt say, wins to get it. It does not split screen the two groups and say WHO, which would then mean WHICH OF THESE TWO GROUPS gets it.
So, somebody wins from RI and gets love, and may be offered a choice to pick someone from RI. I don't think they will mix the two groups on a reward, as that is just a bit too much and is one step away from bringing the jurors in and letting them all party together. Also, it may not be the winner per se who wins love, it may be all three who stay in, you just don't know.
Next premise: WHO means the same on the Murlonia pic: WHICH OF THESE SIX will SACRIFICE. And it may mean plural.
The graphics overlay doesn't have the whole sentence used by the announcer.
"Who will sacrifice" suggests that someone gives up the visit for someone else. But the full teaser when you add audio asks:
Who will sacrifice for it?
That asks who will give something up in order to get IT, the LOVE. If the teaser meant sacrifice for someone else, then the person who sacrifices does not get IT, just the opposite, so I think more likely this is about a trade-off for the Merlonia. How bad do they want it?
It looks to me like the RI folks duel for it, but as producers don't have time for two challenges, the Murlonia are asked if they will give something up in order to get their visits. No free lunch on Survivor.
Now back to the WHO -- that suggests WHICH individuals rather than "will the group make a sacrifice as a group decision." This picture shows their shock at something. A few are smiling or laughing. Terms announced?
1) give up camp essentials, but that would be a group decision, so I'll sideline that one.
2) agree to sit out the immunity competition in exchange for a visit. That would be interesting. We know though that all line up looking ready, and five definitely compete. Natalie is the only one who might not compete. That would say a lot about how much they all need immunity. Also it puts the producers in a place where they might all choose not to play for immunity (hold out a rock), which would be a big problem with this gigantic challenge set already built.
3) Choice like "feast" OR "visit." Feast to get strong and win challenges, or visit with no food, just rice for everyone.
4) You tell me. I'm sure there are more possibilities.
Grant says, it's priceless, man. Reflection on the value of the love from home?
Must not forget that one castaway has an emotional decision brought by treemail, as that needs to fit in the puzzle.
