She could have just shut up when Asim was talking about Paras speaking about his sister's and mother's character. Asim kept saying he has never said anything about anyone's family.
Mahira madam had to open and mouth then to defend her lover boy. Asim is lying sir. He has called me gandi, gandagi many times. Paras was trying to get her to shut up but no she had to open her mouth and make it obvious that Asim was not lying.
Somehow the way Khesari and Abu said after their eviction. MC BC is not even considered gaali in BB. I think thats why Asim was so confident about himself.
