Vansh s revenge is to make her feel what he felt.
Ex:
1.Arrest for a murder which he did not commit.
So in today s epi,He made her feel how it wud be.
2.After Arrest,his death.Made her feel how it is in a coffin.To be alive but be dead.
So next cud be her marriage,she almost got married to kabir
So he wud make her feel that pain by faking marriage with ahaana.
The first cliff fall scene wud be him saving her.Being romantic,deserting her the next day.
Then ridz wud be searching for him,gets to know abt the marriage and then falls from the cliff(second cliff scene in red dress).This time no one saves her.We may get a leap and a separation track I think....
