The fact that Jen nominated a father/daugther combination who haven't spoken in a few years is pretty heartless IMHO.
Heartless? Was it heartless to split up one pair last week and a different pair this week?
The houseguests may be vain but not stupid. They are wasting no time splitting up the pairs.
This is a contest, not a mediation. The tension between those two was probably awful and splitting them up probably benefits everyone including themselves.
Later in the game is fine but doesn't this woman have any compassion?
What is the specific point in the game when a contestant should switch from trying to be compassionate to actually playing the game?
