The problem is, the boybands are both very generic so their only real fanbase comes from the tweens who support anyone going. With District 3 being so overwhelmingly bad this week, the tweens voted in their droves for them thinking they were more at risk and UJ got left behind.
Regardless of my shock at the bottom two, I think the judges gave Jade a really unfair time, on the basis that it was a sing-off, Jade should have been saved.
