I don't care how it's put, i do not believe she was given the same treatment the others were. While others are, "Boring" "Floppy" or "Trashy", she was given "Ran outta gas/steam.." 000aAnd if it were all 100% legit and equal, she never would've made it past prelims. If anyone else did what she did then, they were sent packing -- period.
they obviously don't show the entire practice/rehearsal...i'm sure she was criticized, but it just wasn't shown. and if you watched the last episode, you would see that they did critcize cassie, or at least show footage of it happening.
Notice how no one criticizes Cassie; sheltered much? I wish all the girls had mommies to shield them.
