Not long after, Moon swapped Co-Lab for another band, and the Whangarei boys' dream was over. Kills was entitled to her view. But it was apparent then that she saw things very differently from her other judges.
As she did on Sunday night when she humiliated contestant Joe Irvine for what she saw as the mimicking of her husband Moon.
Irvine did not deserve Kills' vicious tirade.
Ironic too, as neither Kills nor Moon are purveyors of a particular unique musical or fashion style. Controversial judges on X-Factor are nothing new - Simon Cowell has made a career out of being the "bad cop". He has a track record of identifying talent, though, and offers constructive views, as well as his bold opinion.
Irvine did not deserve what he got from Kills on Sunday. It was mean.
Her employer agreed and Kills and husband Moon, who was also made harsh comments, are gone.
And as for Co-Lab, Moon wasn't responsible for their departure, Kills was.
Co-Lab were the victims of poor judgment - it's a shame because, unlike the two sacked judges, they deserve another shot.
