Ok let me clarify myself. i havnt watched today's episode yet but this is what i think:
Angad is actually doing Kripa a favor. HE knows Prithvi is bad and he doesnt want his Kripa to be with Prithvi. Angad knows Kripa wont believe him that P is bad, so he has to act like he wants revenge from Kripa and all that stuff to get Kripa seperated from P.
If all that which i said is true, i fail to understand 1 thing, why didnt he stop Kripa if she actually did sleep with P? HE could have. O well I trust Angad and Kripa is still good 2, both of them need to TALK THINGS OUt, naa?
