Well, I was thinking about this and it suddenly struck me. According to the tape that played when Anitah pressed play on the stereo system, the tape starts off at the moment when A-K are dancing to the song and everything afterwards is recorded....right?
SO if that is the case, Angad had admitted to being Angad BEFORE Prithvi had come. He had told Kripa that yes he was Angad and that he is now Zaib because she killed Angad. Now he is the Zaib that she hates.
So there you go folks, that there was his admission to being Angad. Kripa herself had started to walk away, so i'm thinking that she too had probably decided that that admission was all she needed, and she was leaving to get the tape when Angad stopped her.
All that leads me to conclude that if she already had what she needed from Angad, in regards to him admitting he is Angad then her own admission of still loving Angad COULDNT have been a lie! Angad had stopped her and made her admit her feelings which she did, then after he told her he still hated her she also remembered her plan and probably came out to get the tape.
I hope I didnt confuse you guys, but considering the situation as an aggregation of "ifs" and "maybes" I think Kripa was just out to get a recording out of Angad, just like how Angad got a recording out of Kripa before after she had brought a woman to pretend to be Zaib's gf. She wasnt intending on using his profession of love, because how would she even know that Prithvi would walk in mid-way through her sentence? She had told him she loves him, simply to tell him she loves him; Not to break his heart afterwards, because she already had his admission of being Angad from before.
I still love A-K equally but these are just my thoughts on the matter. Feel free to disagree.😳
