I'm going to discuss both sides of this from hopefully an unbiased POV...
What Jade and Mikkayla said was nasty and Tahan had the right to know. However what Drew repeated wasn't correct. Jade went on to say 'Actually, I would care if she died...but I'm not a fan' and Drew gave no mention of this, essentially making the situation seem worse and more vindictive than it actually was.
Jade admitted to Tahan that something was said along those lines, but had obviously been taken out of context when repeated to her, which is true. Drew admitted to being in the room but denied saying those words to Tahan (not true, you liar)
And now Jade has realised that Drew is repeating things to people, but twisting the words. She is right not to trust him.
Tahan had the right to be upset, but shouldn't be ashamed for showing it.
And in conclusion....these girls need to talk to each other and sort their bloody issues out.
