WTF???
Why did Arisa give Phil/Nick a chance to change their minds?
Nick says "We nominate ourselves". Shocking? Sure. But Arisa should have immediately said "Fine sit down on the block" instead she says "Are you sure?" and gives them a quick second to talk about it? I mean, COME ON, even Nick wanted an extra 30 seconds. Give me a break. At no other time has a host on BB asked any HoH if they were "sure" about their noms.
Does Arisa get no training on what to do in various situations?
