Is it OK to talk about Survivor on this board? Assuming it is, I'll respond...
Yes, Jon is annoying, arrogant, and perhaps too confident in general. HOWEVER, at this stage of the game, the STRONGEST are the most threatening. Jon hardly lies in the "strong" category. At this point, Burton and Rupert are VERY vulnerable.
Voting off Rupert would be unwise at this stage. Rupert is too valuable as a hunter. I haven't seen any of the women's skills as hunters. Lill would likely have the most experience as a scout leader. However, the ladies should consider which guy they'd most trust and would be beneficial in helping them to survive for the remainder of the time.
