Ok, so here I am with a theory that crossed my mind regarding revelations, whenever that happens.
We all know that Pallavi is the typical over generous FL, who does good not just for her own, but also for outsiders, in this case Kirti and her amma.
Leaning on my ITV experience this is my theory about this whole misunderstanding getting resolved. I personally feel Anjali herself, Farhad and Kirti and her mom have a lot to contribute.
Probably, Farhad will do some internal investigation and find out about the truth of the MMS fiasco. And will create a scenario where Anjali would herself blurt out the truth in Raghav's presence and coincidentally Pallavi also happens to be there. After the confession, things go out of hand, and Anjali tries to hurt Raghav with a gun. Pallavi intervenes and gets shot.
Raghav and Farhad take her to the hospital. The family is informed. Probably Kirti and Amma come for a doctor's visit and learn about her condition. This situation becomes ideal for the donor truth and widow truth being revealed. Probably Kirti let's the doctor know or any other family member that Pallavi is an orphan and widow and they are not her family, but in laws. And the blood group won't match. So doctor in turn reveals that Raghav's mother could donate blood to Pallavi and the donor truth rolls out as well.
You know ITV ka favorite habit to bomb phoding all together on ML, who ideally deserves a special Valentine date in hell, for what he is putting Pallavi through. Aisa hi kuch yahaan hoga.
What do you guys think? Please contribute with your theories.
