I think that trust is something that was on and off in the serial, and in real life, it shouldn't be "on and off."
There was sometimes trust between Angad and Kripa, but never full-blown trust, I think. Sometimes I thought Angad trusted Kripa more because he wasn't as suspicious as she was, but then again both did horrible things to each other!! But between the two, I do think that Angad had more trust in Kripa than she did.
People like Kanan, Nishant, Josh, Shabbir... are people whom I really admired because they never changed sides or told lies ..!! They were the only ones I think who were really trustworthy. Even I thought Dadi for sometime was until she did all that hungama.
Will be back later !
