I think Pegleg is restraining himself from telling some of the younger ones to stfu because he doesn't want to make enemies/wants to stay under the radar. He was genuinely shocked when Doug went.
Tinuke knew either Matthew or Laurence must have betrayed her but couldn't quite believe that either of them would. She thought that all the ex-Caletonians would just say yes to anything she and Nathan decided.
Laurence was quite smart not actually voting for T but also not voting Chris. He wanted T to think well of him when she is on the jury. However this may not work since she hasn't yet worked out that Matthew was her betrayer.
Matthew was smart to realise that if he ended up in the final 3 with Tinuke and Nathan then they would discard him and take each other to the final 2. HOWEVER, he has now put a bit of a target on himself as Nathan and Leilani will no longer trust him and will be gunning for him.
Christopher was having a lovely time giggling to himself as first Doug and then Tinuke left while he is still there despite having been seen as dead-man-walking. However his problem is still that NO ONE trusts him!
It will be interesting to see if the new alliance of Matthew, Pegleg, Chris and Hannah lasts and they try to get Nathan out next, who is a big player. Looking at the last few challenges, they need to realise that Christopher, Laurence, Pegleg, Matthew are all pretty good at challenges. It depends who wins the next immunity too. If it's Nathan, do they go back to trying to get Chris out or use him as a voting number against the ex-Caletonians?
It's starting to get good!
