i think shyam knows Khushi has a lead on him and let her follow him.
but before that he has already again poisoned Arnavs mind with khushi and evidence that she has signed is proved against her and arnav is shattered but the ASR in him is not
i feel shyam would have told him that khushu will come her finding him and do natak to show him her love care affection while all the while she is with him in kidnapping him and wants his property and he may have recorded the conversation that khushi and shyam has about how she hate arnav and how she wanted his life destroyed and all the property for her
When khushi finds him ASR will behave loving with her and they will have a romantic time may be even run away and have SR too far fetched and then he will hurt her and ditch her
that will be khushs final destruction as mentioned in the spoiler once before and then when ASR will come to know the truth he will regret his actions and the redemption track will start
khushi may not forgive
oh my weekend free brains are on the run again
