The thing is, we were arguing about this sentence that I wrote: "The problem I have with it (the mentor twist) was illustrated by Kara being targeted only because she was Dan's player. It robs the players of their own game."
So we were clearly talking about nominations.
Frank also was targeted for being Boogie's player, I don't argue against that because it also illustrates why I hate that twist.
You want to know why Joe should have talked to Kara in week 1? How about giving himself more options? If you want to win a game like this, you got to have options and, in week 1, you don't know which option will work best. Therefore, a smart player talks to EVERYONE! Simple really.
PS. The main reason why Kara was voted out wasn't her social game: The House decided to stick it to Willie by keeping his rival. That's something Kara couldn't control so being nominated killed her.
