No, sorry. I just looked at it (I have a DVR)
Rupert, Burton and John hit their spots to become killers.
then  
Sandra hit her spot becoming a killer 
 then Burton hit Rupert for a 3x making him lose his 1)killer status, and 2) 2 lives.  
  
Then on Sandra's  next turn she hit Rupert to force him out.   
  
 
Then, in later shots Burton hit Sandra for a triple, leaving her with only her
 safety, on her next she hit Burton but because she was no longer a killer it didn't count for anything. 
 Sandra's  shot counted against Rupert because she had killer status at the time.
