This is my theory guys
Amma’s peanut allergy was drama to check if Kirti could drive, my reasons
1. Pallavi was quite chill & she only told that there r no drivers & will tell Farhad to bring doctor
2. If Amma really had such allergy obviously Raghav-Kirti would know
3. Amma was overhearing Raghav-Kirti conversation in her room abt fact that Kirti cnt drive
Nxt step, Pallavi-Farhad gt Kirti to admit that she was at accident location & in the car
Now, Pallavi must b very clear that it must be Sunny so she called police to arrest Kirti (taaki usse pata chale k Sunny kitna faltu hai)
But Raghav game Bigad dega, khudke confession se replace karke !! & Kirti b daffar I rahegi
So she’ll goto jail to tell RR everything 😊
