I've seen all seasons of Survivor. There have been 20 so far, and Nicaragua is the 21st. In this season, the two tribes are divided by the older players (over 40) and the younger players (under 30).
Let me just say early on that after watching last season's Survivor Heroes vs Villains, the first episode of Survivor Nicaragua was quite disappointing mainly because not much seemed to happen. It was great to watch Survivor again after waiting for a bit, but all in all this was an average episode.
During the immunity challenge, the young tribe won and the old tribe went to tribal council where they voted out a woman named Wendy who looked young but was actually about 48. My opinion was that the main problem with her is that she was not physically strong (it is normal in Survivor for weaker players to be voted out early) and because she did not bond well with the rest of her tribe. She knew that she was different and tried hard to bite her tongue and not say much. She spent much of her time working by herself rather than bonding with others players. It is important for players to not only try to work and to show that they are valuable and strong but to also put some effort into socializing with others. During the tribal council she came out strong and effectively blamed everyone else in her tribe for not being nice to her. After her outburst I was sure that she would go. You don't demand respect from others. You earn it.
The preview for the second episode sort of suggests that the younger tribe (called La Flor) will go to tribal council and there will be massive argumetns involving one of the younger blonde male players, pejoratively called Fabio.
