Confused about Ciera I know this sub seems to love Ciera, but I’m thoroughly confused at her game play (I’m watching for the first time)
At F7, she’s approached by Hayden and Caleb to flip on Tyson, but she decides to stay loyal to him, to the point of telling him the plan.  
At F6, she draws rocks because Hayden convinces her that she’s number 4 in the alliance.  Was this the first time she thought about that?   Makes zero sense.  
Had she voted out Tyson at F7, she wouldn’t have had to play for rocks.   This effectively blows up any chance she has with Tyson’s alliance anyway.
I know I know, but “Tyson played his idol”.   True, but he played it because Ciera told him he was targeted.   I don’t think he plays it without that info.  
What am I not understanding?
