Bloopers
1) When Arnab visited the memorial of Sugandh and Pia, the tombstone had Piyashree Jaiswal engraved into it. But Arnab keeps saying that his supposedly dead daughter's name is Piyali.
2) Arnab says that he regards Pia as his own daughter but the thought never occurs to him that there is eerie similarity between Pia's name and age and his own dead daughter.
3) As someone pointed out in other post that Maithili is an Indian princess but she wears a Victorian dress not saree or lehengas.
4) Maithili is supposedly daughter of very rich king yet she wears no expensive looking jewelries.
5) Abhayendra costume and haircut (too neat and identical to present day Abhay's).
6) The flashback that Abhay had where he and Maithili were together in bed. If Maithili was the princess, she would have lots of maids in her service 24/7 who would constantly keep the king informed of her whereabouts. Absolutely no chance of spending night together with a guy!
That's all! I can think of now.
