Dont know what her strategy is? saving SKY as an act of good-will????
Her USP is " to voice out her opinion" which always contradicts and rubs Sky the wrong way. she is the only person in the house, who can show Sky, his real place (garbage). Sky now, is acting cool and gaining limelight, as everything is going as per his plans. He needs to be rubbed on the wrong side inorder for him to show his true colors.
Mehek should team up with Sid to bring down sky and his group before she runs out of company.
