Honestly speaking I did not find anything rude in Antara's behaviour in that episode. She was in bottom 3 for the first time and it is bound to upset her as she is only a human being not a machine. On top of that when she told Meenal that "woh to hamesha yah pe ati hain" she actually meant to say peoples judgement aginst Meenal is not good. Also whu do all anit-Antara people pick up that selective remarks, why don't you mention that Antara also told Meenal that "I cannot live without you"
