When pia went to abhay's place to give him cake (which makes no sense because she was suppose to take revenge) at that time mr. raichand asked to his wife and son that no one told him that pia's face is exactly like maithili. The thing i didnt understood is in party when abhay proposed pia for dance which was part of appolise according to abhay,at that time mr.raichand was there and he saw full dance. Dint he noticed pia at that time? I think when abhaya and pia were dancing, everyone was watching them only including mr.raichand infact he is witness of full dance.
