Another far fetched thought, based on how communicative this family is. What if Dhara and Raavi question Krish and he tells them everything about scaring Rishita and Shiva pressuring him. Then Krish along with all 3 of his Bhabi reverses the prank on Shiva.
Rishita pretends to be scared and needs medical attention and Shiva feels all guilty and apologetic. This will help Shiva and Rishita bond, and ShiVi bond as well and nobody gets any scolding.
I thought the same!! Why else would Raavi tell Dhara? There must be this angle.
