Most of this was in the CBS episode summary but Zap2it gives some new information.DESPERATION SETS IN WHEN A TRIBE MEMBER CONSIDERS TURNING ON A FELLOW MEMBER, ON "SURVIVOR: AFRICA," NOV. 15
"I'd Never Do It to You" -- One age-aligned group fights to save one of its own, while another considers betrayal, on SURVIVOR: AFRICA, Thursday, Nov. 15 (8:00-9:00 PM, ET/PT) on the CBS Televison Network.
A "quiet" conversation is overheard by the wrong person; a tribe member many seemed to dislike turns out to be a pretty good teacher, and a sixth individual is voted out of the tribe.
Obviously, the mallrats try to save Lindsey. Sounds like someone in another group considers betrayal. Doesn't say that the tribe member does betray only considers. Lex and Tom are tight. Kelly has said she feels like an outsider with them. Could be she "considers" voting with the mallrats.
