I think it can be done. Monday's episode can show Aarti following Yash, finding them in a compromised position, thinking the worst and being absolutely traumatised. Yash will be furious at Ishita for making him look like a cheater and he will run off to try and convince Aarti that nothing was going on and that Ishita was only helping to look for Aayu and he was with her. In the process, Aarti might blurt out what she knows about Ishita's feelings and say, "how can I believe you? I saw with my own eyes..." Ahem, cue wake-up call for Yashji. 😆 I want this scene to be totally intense with Aarti losing her cool entirely and Yash being at a total loss to reach out to her.
Then Tuesday we can see Yash manipulating Ishita, maybe pretending to fall for her trap and then BAM, causing her to do her own parda faash in front of the whole family and giving her a piece of his mind. He should say in front of everyone that he was wrong to doubt Aarti on the day of the kidnapping; he always knew it wasn't her fault. And then he should say he knows where Aayu is and tell the story of how Ishita left him in an orphanage and a young couple adopted him... And freeze.
Then Wednesday I want a full emotional episode with Paridhi apologising to Aarti, returning Aayu and then a Yash-Aarti-Aayu reunion where Aarti apologises for doubting Yash and tries to blame herself again and he has none of it, telling her that no matter what they have to trust each other now, etc etc.
Then Thursday and Friday can be reserved for fluff! 😊
