After the dancing Khushi tries to open the sindoor but open's it forcefully and ends up getting hurt with some of the sindoor falling near her eye. Than we see Arnav slowly blow away the pain. For me this symbolizes the current situation with Khushi trying desperately to find out who Aarav's father - in her haste to unfold the truth she will end up getting hurt. Arnav will be the one to see her pain and will try and soothe it with his love and care.
After the sindoor scene we saw Khushi while trying to crap the plate will get stuck to Arnav via her earring. Arnav was again the one to untangle her earring from his shirt. I see this as Arnav and Khushi will clash over Aarav situation with Arnav not accepting Aarav and with Khushi trying to make him do it. But they will be at stalemate where they both will be hurting because of this - the situation will continue until the time Arnav decides enough is enough and will untangle the mess. He will do it as smoothly and pain free as possible for Khushi.
Last we came to the scene where Khushi almost fell in to the pool and Arnav managed to grab her as usual. Khushi told him to be careful to which Arnav promised that he will always be careful. I see this as the fact that Khushi will do something so drastic that she might end up getting seriously hurt but Arnav will be there for her and will save her in the nick of time. But while thinking of her safety Arnav might end up forgetting to be careful and watch his back. But Khushi will remind Arnav of that and Arnav will remember that promise before it becomes too late.
Under no circumstances do I believe that Arnav and Khushi will separate - they will hurt, fight and love together and will try solve this Aarav situation individually first but then realize that they need to handle it together.
